It with the humanity these which in the agricultu re, the industry society created only is strengthens the phy sical labor the tool to compare, got up the quantitive leap ,entered the information society for the humanity to laythe foundation.After 6 years, in 1952, computer technology applied to t he engine bed , the first numerical control engine bed were born in US. From this time on, the traditional engine bed has had the archery target change. Since nearly half centu ry, the numerical control system has experienced two stages and six generation of development.1.1 Numerical control (NC) stage (1952 ~ 1970)The early computer operating speed is low, was not big to then science computation and the data processing influence ,but could not adapt the engine bed real-time control reques t.The people can not but use numeral logic circuit "to buil d"to become an engine bed special purpose computer to take the numerical control system, is called the hardware connecti onnumerical control (HARD-WIRED NC), Jian Chengwei numerical c ontrol (NC). Along with the primary device development, this stage has had been through repeatedly three generations, na mely 1952 first generation of -- electron tube; 1959 second generation of -- transistor; 1965 third generation -- small scale integration electric circuit.1.2 Computer numerical control (CNC) stage (in 1970 ~ presen t)In 1970, the general minicomputer already appeared and th e mass production. Thereupon transplants it takes the numeric al control system the core part, from this time on entered the computer numerical control (CNC) the stage ("which should have computer in front of the general" two characters to ab breviate). In 1971, American INTEL Corporation in the world first time the computer two most cores part -- logic units and the controller, used the large scale integrated circuit technology integration on together the chip, called it the m icroprocessor (MICROPROCESSOR), also might be called the centr al processing element (to be called CPU).The microprocessor is applied to 1974 in the numerical c ontrol system. This is because minicomputer function too stro ng, controlled an engine bed ability to have wealthily (therefore once uses in controlling the multi- Taiwan engine bed at that time, called it group control), was inferior to use d the microprocessor economy to be reasonable. Moreover then small machine reliability was not ideal. The early microproce ssor speed and the function although insufficiently are also high, but may solve through the multi-processor structure. Because the microprocessor is the general-purpose calculator core part, therefore still was called the computer numerical control.In 1990, PC machine (personal computer, domestic custom had called microcomputer) the performance has developed tothe very high stage, may satisfiedly take the numerical cont rol system core part the request. Thenumerical control system henceforth entered based on the PC stage. In brief, the computer numerical control stage has also experienced three generations. Namely 1970 fourth generat ion of -- minicomputer; 1974 five dynasties -- microprocessor and 1990 sixth generation -- (overseas was called PC-BASED) based on PC.Also must point out, although overseas already renamed as the computer numerical control (namely CNC).Also must point out, although overseas already renamed as the computer numerical control (namely CNC), but our countr y still the custom called the numerical control (NC). Theref ore we daily say "numerical control", the materially already was refers to "computer numerical control".1.3 the numerical control future will develop tendency1.3.1 open style continues to, to develop based on the PC sixth generation of directionThe software and hardware resources has which based on P C are rich and so on the characteristic, the more numerical controls serial production factory can step onto this path. Uses PC machine to take at least its front end machine, pr ocesses the man-machine contact surface, the programming, the association .Question and so on net correspondence, undertakes the num erical control duty by the original system. PC machine has the friendly man-machine contact surface, will popularize to all numerical controls system. The long-distance communication, the long-distance diagnosis and the service will be more common.1.3.2 approaches and the high accuracy developmentThis is adapts the engine bed to be high speed and the high accuracy direction need to develop.1.3.3 develops to the intellectualized directionAlong with the artificial intelligence in the computer do mainunceasing seepage and the development, the numerical control system intellectualized degree unceasingly will enhance.(1) applies the adaptive control technologyThe numerical control system can examine in the process some important information, and the automatic control system related parameter, achieves the improvement system running sta tus the goal.(2) introduces the expert system instruction processingThe skilled worker and expert's experience, the processing general rule and the special rule store in the system, take the craft parameter database as the strut, the establishmenthas the artificial intelligence the expert system.(3)introduces the breakdown to diagnose the expert system(4) intellectualized numeral servo driveMay through the automatic diagnosis load, but the automat ic control parameter, causes the actuation system to obtain the best movement.Second, engine bed numerical control transformation necessi ty.2.1 microscopic looks at the transformation the necessityFrom on microscopic looked below that, the numerical cont rol engine bed has the prominent superiority compared to the traditional engine bed, moreover these superiority come from the computer might which the numerical control system contain s.2.1.1 may process the traditional engine bed cannot proce ss the curve, the curved surface and so on the complex com ponents.Because the computer has the excellent operation ability, may the instant accurately calculate each coordinate axis ins tant to be supposed the movement physiological load of exerc ise, therefore may turn round thesynthesis complex curve or the curved surface.2.1.2 may realize the processing automation, moreover is the flexible automation, thus the efficiency may enhance 3 ~ 7 times compared to the traditional engine bed.Because the computer has the memory and the memory prope rty, may the procedure which inputs remember and save, thenthe order which stipulated according to the procedure automat ic carries out, thus realization automation. The numerical co ntrol engine bed so long as replaces a procedure, may reali ze another work piece processing automation, thus causes the single unit and the small batch of production can automate, therefore is called has realized "flexible automation".2.1.3 processings components precision high, size dispersion d egree small, makes the assembly to be easy, no longer needs "to make repairs".2.1.4 may realize the multi- working procedures centralism, r educes the components in engine bed between frequent transpor ting.2.1.5 has auto-alarm, the automatic monitoring, automatic comp ensation and so on the many kinds of autonomy function, thu s may realize long time nobody to safeguard the processing.2.1.6 advantage which derives by above five.For example: Reduced worker's labor intensity, saved the labor force (a person to be possible to safeguard the multi - Taiwan engine bed), reduced the work clothes, reduced the new product trial manufacturing cycle and the production cycl e, might to the market demand make rapid reaction and so o n.Above these superiority are the predecessor cannot imagine, is an extremely significant breakthrough. In addition, the en gine bed numerical control carries out FMC (flexible manufact ure unit), FMS (flexible manufacture system) as well as CIMS (computer integration manufacture system) and so on the enter prise becoming an information based society transformation foundation. The numerical control technology already became the manufacturing industry automation the core technology and the foundation technology.2.2 great watches the transformation the necessityFrom on macroscopic looked that, the industry developed c ountry armed forces, the airplane weapon industry, in the en d of the 70's, at the beginning of the 80's started the l arge-scale application numerical control engine bed. Its essen ce is, uses the information technology to the traditional in dustry (including the armed forces, airplane weapon industry) carries on the technological transformations. Except that uses outside the numerical control engine bed, FMC, FMS in the m anufacture process, but also includes in the product developm ent carries out CAD, CAE, CAM, the hypothesized manufactureas well as carries out MIS in the production management (ma nagement information system), CIMS and so on. As well as in creases the information technology in its production product, including artificial intelligence and so on content. Because uses the information technology to the country foreign troops, the airplane weapon industry carries on the thorough transfor mation (to call it becoming an information based society), f inally causes them the product in the international military goods and in the goods for civilian use market the competit ive power greatly is the enhancement. But we in the informa tion technology transformation tradition industry aspect compar ed to the developed country to fall behind approximately for 20 years. Like in our country engine bed capacity, numerical control engine bed proportion (numerical control rate) to 199 5 only then 1.9%, but Japan has reached 20.8% in 1994, therefore every year has the massive mechanical and electrical products import. This also on from on macroscopic explained the engine bed numerical control transformation necessity. Tho rd, the numerical control transformation content and superiorl y lacks3.1 Transformation industry startingIn US, Japan and Germany and so on the developed countr y, their engine bed transforms took the new economical growt h profession, thrives abundantly, is occupying the golden age .As a result of the engine bed as well as the technical u nceasing progress, the engine bed transformation is "the eter nal" topic. Our country's engine bed transformation industry, also enters from the old profession to by the numerical c ontrol technology primarily new profession. In US, Japan, Ger many, have the broad market with the numerical control techn ological transformations engine bed and the production line, has formed the engine bed and the production line numerical control transformation new profession. In US, the engine be d transformation industry is called the engine bed regenerati on(Remanufacturing) industry. Is engaged in the regeneration ind ustry famous company to include: The Bertsche engineering fir m, the ayton engine bed company, Devlieg-Bullavd (are valuabl e) serves the group, the US equipment company and so on. T he American valuable company has set up the company in Chin a. In Japan, the engine bed transformation industry is calle d the engine bed to reequip (Retrofitting) industry. Is enga ged in the reequipment industry famous company to include: B ig indentation project group, hillock three mechanical companies, thousand substitute fields labor machine company, wild engineering firm, shore field engineering firm, mountain this engineering firm and so on. 3.2 Numerical control transformat ion contentThe engine bed and the production line numerical control transformation main content has following several points: First is extensively recovers the function, to the engine bed, the production line has the breakdown partially to carr y on the diagnosis and the restoration;Second is NC, the addend reveals the installment on the ordinary engine bed, or adds the numerical control system, transforms the NC engine bed, the CNC engine bed;Third is renovates, for increases the precision, the effi ciency and the automaticity, to the machinery, the electricit y partially carries on renovates, reassembles the processing to the machine part, extensively recovers the precision; Does not satisfy the production request to it the CNC system to carry on the renewal by newest CNC;Fourth is the technology renews or the technical innovati on, for enhances the performance or the scale, or in order to use the new craft, the new technology, carries on the b ig scale in the original foundation the technology to renew or the technical innovation, the great scope raises the leve l and the scale renewal transformation. The new electri cal system transforms after, how carries on the debugging as well as the determination reasonable approval standard, also is the technology preparatory work important link. The debugg ing work involves the machinery, the hydraulic pressure, the electricity, the control, and so on, therefore must carry onby the project person in charge, other personnel coordinate. The debugging step may conform to simplicity to numerous, fr om infancy to maturity, carries on from outside to in, afte r also may the partial overall situation, after first the s ubsystem the 3.3 The numerical control transformation superior ly lacks 3.3.1 reduced investment costs, the date of deliv ery are short With purchases the new engine bed to comp are, may save 60% ~ 80% expense generally, the transformatio n expense is low. Large-scale, the special engine bed especi ally is specially obvious. The common large-scale engine bed transforms, only spends the new engine bed purchase expense 1/3, the date of delivery is short. But some peculiar circu mstances, like the high speed main axle, the tray automatic switching unit manufacture and the installment too requires a lot of work, costs a great deal of money, often transforms the cost to enhance 2 ~ 3 times, with purchases the new engine bed to compare, only can economical invest about 50 %.3.3.2 machine capability stable are reliable, the structure i s limitedUses foundation and so on lathe bed, column all is heav y but the firm casting component, but is not that kind of welding component, after the transformation engine bed perform ance high, the quality is good, may take the new equipment continues to use many years. But receives the original mecha nism the limit, not suitably makes the unprecedented transfor mation. 3.3.3 familiar understood the equipment, is advantag eous for the operation serviceWhen purchases the new equipment, did not understand whether the new equipment can satisfy its processing request. Th e transformation then otherwise, may precisely calculate the engine bed the processing ability; Moreover, because many yea rs use, the operator already understood to the engine bed c haracteristic, uses and services the aspect to train the tim e in the operation short, effective is quick. The transforma tion engine bed as soon as installs, may realize the capaci ty load revolution. 3.3.4 may fully use the existing condi tionMay fully use the existing ground, does not need to lik e buys when the new equipment such to have reto construct the ground. 3.3.5 may use the newest control technology enhances the production equipment the automated level and the efficiency, improves the equipment quality and the scale, alters to the old engine bed now the horizontal engine bed. Fourth, numerical control system choiceWhen the numerical control system mainly has three kind of types, the transformation, should act according to the sp ecial details to carry on the choice.4.1 Step-by-steps the open system which the electrical ma chinery drivesThis system servo drive mainly is step-by-steps the elect rical machinery, the power step-by-steps the electrical machin ery, the battery solution pulse motor and so on. Entering s ends out which by the numerical control system for instructi on pulse, after the actuation electric circuit control and t he power enlargement, causes to step-by-step the electrical m achinery rotation, through gear vice- and ball bearing guide screw vice- actuation executive component. So long as the control command pulse quantity, the frequency as well as the circular telegram order, then may control the executive compo nent movement the displacement quantity, the speed and the h eading. This kind of system does not need the physical loca tion and the velocity feedback which obtains to the input e nd, therefore called it the open system, this system displac ement precision mainly decided in step-by-steps the electrical machinery angular displacement precision, transmission part and so on gear guide screw pitches the precision, therefore the system displacement precision is low.This system structure simple, debugging service convenient, work reliable, cost low, is easy to reequip successfully.4.2 The asynchronous motor or the direct current machine drive, diffraction grating survey feedback closed loop numer ical control system .This system and the open system difference is: Physical location feedback signal which by position detector set and so on the diffraction grating, induction synchromesh obtains, carries on the comparison as necessary with the given value, two interpolations enlargements and the transformation, the ac tuation implementing agency, by the speed which assigns turns towards the elimination deviation the direction movement, unti l assigns the position and the feedback physical location in terpolation is equal to the zero. The closed loop enters fo r the systemEnters for the system complex in the structure compared to the split-ring, the cost is also high, requests strictly to the environment room temperature. The design and the debu gging is all more difficult than the open system. But mayobtain compared to the split-ring enters for a system higher precision, quicker speed, actuation power bigger characteristic target. May act according to the product specification, decid ed whether uses this kind of system.4.3 The direct current servo electrical machinery drives, encoder feedback semi-closure link numerical control system .Half closed-loop system examination part installs in among passes in the moving parts, indirectly surveys the executive component the position. It only can compensate a system ring circuit interior part of part the error, therefore, its prec ision compared to closed-loop system precision low, but its structure and the debugging all compares the closed-loop syst em to be simple. In makes the angular displacement examinati on part and the speed examination part and the servo electr ical machinery time a whole then does not need to consider the position detector set installs the question.The current production numerical control system company fa ctory quite are many, overseas famous company like German SI EMENS Corporation,Japanese FANUC Corporation; Native corporation like China Mount Everest Corporation, Beijing astronautics eng ine bed numerical control system group company, Central China numerical control company and Shenyang upscale numerical contr ol country engineering research center.When choice numerical control system mainly is each kind of precision which the engine bed must achieve after the nu merical control transformation, actuates the electrical machine ry the power and user's request.Fifth in the numerical control transformation the mainmechanical part reequips the discussionA new numerical control engine bed, must achieve in the design that, Has the high static dynamic rigidity; Movement vice- between friction coefficient small, the transmission is ceaseless; The power is big; Is advantageous for the operati on and the service. When engine bed numerical control transf ormation should meet the above requirements as far as possib le. Cannot think the numerical control installment and the o rdinary engine bed connects in has met the numerical control engine bed requirements together, but also should carry on t he corresponding transformation to the major component to ena ble it to achieve the certain design request, can obtain th e anticipated transformation goal. 5.1 skids guide railSaid to the numerical control lathe that, the guide rail besides should have the conventional lathe guidance precision and the technology capability, but also must have good bears the friction, the attrition characteristic, and the reduction but sends the dead area because of the friction drag. At t he same time must have the enough rigidity, by reduces the guide rail to distort to processes the precision the influen ce, must have the reasonable guide rail protection and the lubrication.5.2 gearThe common engine bed gear mainly concentrates in the headstock and the gear box.In order to guarantee the transmission precision, on the numerical control engine bed uses the gear precision class i s all higher than the ordinary engine bed. Must be able to achieve the ceaseless transmissionin the structure, thus transforms time, the engine bed maingear must satisfy the numerical control engine bed the reque st, by guarantees the engine bed processing precision.5.3 skids the guide screw and the ball bearing guide screwThe guide screw transmission relates directly to the tran smission chain precision. The guide screw selects mainly is decided requests and drives the torque request in the job p recision. Is not used by job precision request Gao Shike skids the guide screw, but should inspect the original guide screw attrition situation, like the pitch error and the pitc h accumulative error as well as matches the nut gap. The o rdinary circumstances skid the guide screw to be supposed no t to be lower than 6 levels, the nut gap oversized then r eplaces the nut. Uses skids the guide screw relative ball b earing guide screw price to be low, but satisfies the pre cision high components processing with difficulty.The ball bearing guide screw rubs loses slightly, the ef ficiency is high, its transmission efficiency may above 90%; Precision high, the life is long; When start moment of forc e and movement the moment of force approaches, may reduce t he electrical machinery to start the moment of force. Theref ore may satisfiedly compare the high accuracy components proc essing request. 5.4 safe protectionThe effect must take the security as a premise. Transfor ms in the engine bed must take the corresponding measure ac cording to the actual situation, cuts noticeable. The ball b earing guide screw vice- is the precision part, when the wo rk must take strict precautions against the dust is speciall y the scrap and the hard sand grains enters the roller conveyer. On longitudinal guide screw also coca overall sheet i ron safety mask. The big carriage with skids two end surfac es which the guide rail contacts to have to seal, prevented absolutely the flinty granulated foreign matter enters the sl iding surface damage guide rail.Sixth, After the engine bed electrical system transformati on, to operates, the programmers inevitably brings the new r equest. Therefore ahead of time carries on new system knowle dge training to the operator and the programmers to be extr emely important, after otherwise will affect the transformatio n the engine bed rapid investment production. The training c ontent should include the new operation kneading board dispos ition, the function, the instruction meaning generally; New s ystem functional scope, application method and with old syste m difference; Maintenance maintenance request; Programming stan dard and automated programming and so on. The key point is makes, gets a good grasp of the operating manual and the p rogramming instruction booklet.the numerical control transforms se Transforms the scope according to each equipment differently, must beforehand desig n the connection partial transformations, if transforms comple tely, should design the electro-mechanical transformation conne ction, the operation kneading board control and the dispositi on, the interconnection partial contacts, the parameter measur ing point, services the position and so on, the request ope rates and services conveniently, reasonable, the line moves t owards, center the small junction smoothly few, the strong a nd the weak electrical noise is smallest, has the suitable allowance and so on. Partial transformation, but also needsto consider the new old system the performance match, the v oltage polarity and the size transformation, install the posi tion, the digital-analog conversion and so on, when the nece ssity must manufacture the transformation connection voluntaril y.veral examples1st, transforms the X53 milling machine with SIEMENS 810MIn 1998, the company invested 200,000 Yuan, with German Simens the 810M numerical control system, the 611A exchange servo drive system sds was the X53 milling machine carries on X, Y, the Z three axle numerical control transformation to a company's model; Retained the original main axle system and the cooling system; The transformation three axle has us ed the roller lead screw and the gear drive organization on the machinery.

电动机控制中英文对照外文翻译文献
电动机控制中英文对照外文翻译文献(文档含英文原文和中文翻译)原文：Control of Electric winchFor motor control, we know the best way is to use the style buttons to move the many simple manual console. And this console, in some applications may still be a good choice, as some complex control headache can also be used. This article describes in your design, build or purchase winch controller, you have the motor's basic electrical equipment and you will need to address the user interface command addressed.First, the manual should be a manual control console type, so if you remove your finger buttons, hoist will stop. In addition, each control station equipped with an emergency need to brake, hoist the emergency brake to cut off all power, not just the control circuit. Think about it, if the hoist at the stop, it did not stop, you do need a way to cut off the fault line protection power. Set the table in the control of a key operated switch, is also a very good idea, especially in the line leading to theworkstation can not control, you can use the switch.(in the design of the console, even the simplest manual console, but also consider setting by specialized personnel to operate the safe operation of the keys.) Constant speed motor controlFor a fixed speed winch actual control device is a three-phase starter. Turn the motor is reversed, by a simple switch controlled phase transformation sequence from ABC to CBA. These actions are completed by two three-pole contactor-style, and they are interlocked, so that they can not be simultaneously closed. NEC, required in addition to overload and short circuit protection devices. To protect the motor against overload due to mechanical effects caused by overheating in the heat to be installed inside the starter overload delay device. When the heat overload delay device overheating, it has a long double off the metal motor power. In addition In addition, you can also select a thermistor can be installed in the motor winding way, it can be used to monitor motor temperature changes. For the short-circuit protection, we generally used by motor fuses to achieve.A linear current independent contactors, the contactors are configured should be more than the current main circuit contactor, so as to achieve the purpose of redundancy. This sets the current contactor is controlled by the security circuit, such as: emergency brake and the more-way limits.We can use the limit switches to achieve the above operation. When you reach the end of the normal travel limit position, the hoist will stop, and you can only move the winch in the opposite direction (ie, the direction away from the limit position.) There is also need for a more limited way just in case, due to electrical or mechanical problems, leaving the operation of hoist limit bit more than normal. If you run into more limiter, linear contactor will open, therefore, can not be driven winch will exceed this limit position. If this happens, you need to ask a professional technician to check the lead to meet the more specific reasons limiter. Then, you can use thestarter toggle switch inside the elastic recovery process to deal with more problems, rather than tripping device or a hand-off the current contacts.A necessary condition for speedOf course, the simple fixed speed starter is replaced by variable speed drives. This makes things start to get interesting again! At a minimum, you need to add a speed control dial operation platform. Joystick is a better user interface, because it makes you move parts of a more intuitive control.Unfortunately, you can not just from your local console to send commands to control the old variable speed drives, in addition, you can not want it in the initial stages, will be able to enhance the safe and reliable and decentralized facilities. Most of the variable speed drive can not achieve these requirements, because they are not designed to do upgrading work. Drivers need to be set to release the brake before the motor can generate torque, and when parking, that is, before the revocation of torque, the brake will be the first action.For many years, DC motors and drives provide a number of common solutions, such as when they are in a variety of speeds with good torque characteristics. For most of the hoist of the large demand for DC motor is very expensive, and that the same type of AC motor than the much more expensive. Although the early AC drives are not very useful, as they have a very limited scope of application of the speed, but produced only a small low-speed torque. Now, with the DC drives the development of low cost and a large number of available AC motors has led to a communication-driven revolution.Variable speed AC drives in two series. Frequency converter has been widely known and, indeed, easy to use. These drives convert AC into DC, and then, and then convert it back to exchange, the exchange after the conversion is a different frequency. If the drive produced the exchange of 30Hz, 60Hz a normal motor will run at half speed. Theoretically, this is very good, but in practice, this will have a lot of problems. First of all, a typical linear motor 60Hz frequencies below 2Hz 3Hz area or there will be errors, and start cog (that urgent push, yank), or parking. This will limit your speed range lower than 20:1, almost not adapted to the operational phase of the fine adjustment. Second, many low-cost converter is not able to provide the rated torque at low speeds. Use of these drives, will result in the rapid move to upgrade the components or complete failure, precisely, when you try to upgrade a stable scientific instruments, you do not want to see this situation. Some new inverter is a closed-loop system (to get feedback from the motor to provide a more accurate speed control), and the motor will work quite well.Another series of AC drives is the flow vector type drive. These components require installation of the spindle motor encoder, encoder makes use of these drivescan accurately monitor the rotation of the motor armature. Processor accurately measured magnetic flux vector values that are required to make the armature at a given speed rotation. These drives allow infinite speed, so you actually can produce at zero speed to rated torque. These drives provide precise speed and position control, so these drives in high performance applications to be welcomed.(Based on PLC controllers provide system status and control options. This screen shows the operator full access to the nine-story elevator enhance the control panel.) PLC-based systemsIs the full name of a PLC programmable logic controller. First of all, PLC controller developed to replace the fifties and sixties-based industrial control system relay, they work in harsh industrial indoor environments. These are modular systems that have a large variety of I / O modules. The modular system can easily achieve the semi-custom hardware configuration assembled, and the resulting configuration is also very reasonable price. These modules include: position control module, the counter, A / D and D / A converter, and a variety of physical state or physical contact with closed output module. Large number of different types of I / O components and PLC module property makes it an effective way to assemble custom and semi custom control system.The biggest shortcoming of PLC systems is the lack of the real number of display to tell you what is being done and the PLC on the PLC program to help you.T he first is professional entertainment for the large-scale PLC system is one of the original in Las Vegas, MGM (now Bailey Company) of the riding and carriage system. Many manufacturers offer a standard PLC-based semi-automated acoustic systems and a host of signs, set the location of the command line interpreter, and the upgrading of the control system is also available. Using standard modules to set user-defined system configuration capability is based on the PLC controller of the greatest advantage.High-end controllerFor complex transmission, the controller became complex, more than speed, time and location control. They include complex instructions to write and record the movement contour, and the processing can immediately run the ability to multi-point instructions.Many large opera house is toward the direction of point lift system, where each one is equipped with a rope to enhance independent winches, rope equivalent to those of each dimmer circuit. When more than one hoist is used to enhance the individual part, the hoist must be fully synchronous, or the load to shift, so will lead to a separate winch becomes the risk of overload. Control system must be able to be selected to keep pace winch, or a hoist winch is not able to maintain synchronization with the other, can provide the same high-speed parking capacity. For a typical speed of 240 ft / min and a winch to maintain the rate of error of between 1 / 8 points of equipment, you only have less than three microseconds of time to identify problems and try to correct the error The hoist speed, make sure you fail, you start all the winch stop the group. This will require a large amount of computation, fast I / O interface, and easy to use to write software.For large rope control system has two very different solutions. The first is to use a separate console, the problem in general terms, this console should be installed in the appropriate location of the operator perspective. However, this not only from one angle to another angle, but still can not get an instruction to another instruction from the control. These difficulties have been partially resolved. Installed in different locations through the use of video cameras, and these cameras connected to the three-dimensional display graphics, these graphics enables the operator to observe from the perspective of any of the three coordinates in the expected direction of rope movement. These operators can make from a console for him at the actual angle, or closed circuit camera practical perspective, to observe the movement of the rope on the screen. For the complex interrelated moving parts, makes the implementation of the above observation Failure to control and find out easier.Another solution to the problem is a distributed system that uses multiple light console. This will allow the different operators in the same way the different aspects of control gear, we have improved the manual control device. A vivid example is the flower in a vegetable market in central London, the Royal Opera House, the program uses the above, where the control console 240 with ten motors. Each console has five playback device, and has been open, so that each motor has been assigned to a single console. An operator and a console can control all the devices, however, often may be running a console platform screen upgrade, another console is a console on the transmission device, and the third console is used to the necessary backgroundin the background image down.(edge-type portable console allows the operator many advantages from the start to control the movement of the machine, and provide three-dimensional image display.)ConclusionA huge change in the rope control system, a workstation has been developed from a push-button to complex multi-user computerized control system. When the control system to buy rope, you can always find to meet your needs. Control system performance is the most important security and reliability. These are the true value of the property, and you can expect the price to buy a suitable way of security. With a certain product manufacturers to work, he will make you know how to install it. And he will make contact with you and the users, those users have with similar requests.译文：电动卷扬机的控制对于电动机的控制，我们所知道的最好的方式就是使用由许多点动式按钮组成的简单的手工操作台。

The drive trains of thelaser-cutting machine are composed of belt-drives. The elastic servomechanism can be described by a two-mass system interconnected by a spring. Owing to the presence of elasticity, friction and disturbances, the closed-loop performance using a conventional control approach is limited.

Rapid dynamic behaviour and accurate position trajectory tracking are of the highest interest. Applications such as machine tools have to satisfy these high demands. Rapid movement with high accuracy at high speed is demanded for laser cutting machines too. This paper describes motion control algorithm for a low-cost laser-cutting machine that has been built on the base of a planar Cartesian table with two degrees-of-freedom (Fig. 1). The drive trains of the laser-cutting machine are composed of belt-drives with a timing belt. The use of timing belts in the drive system is attractive because of their high speed, high efficiency, long travel lengths andlow-cost (Haus, 1996). On the other hand, they yield more uncertain dynamics and a higher transmission error ( Kagotani, Koyama & Ueda, 1993). Consequently,belt-drives suffer from lower repeatability and accuracy. Moreover, the belt-drive dynamics include more resonance frequencies, which are a destabilising factor in a feedback control (Moon, 1997). Therefore, a conventional control approach like PI, PD or PID control fails to achieve acceptable performance. Plant parameter variations, uncertain dynamics and load torque disturbances, as well as mechanical vibrations, are factors that have to be addressed to guarantee robust system stability and the high performance of the system. An advanced robust motion control scheme is introduced in this paper, which deals with the issues related to motion control of the drives with timing belts. The control scheme is developed on the basis of the motion control algorithm introduced by Jezernik, Curk and Harnik (1994). It possesses robust properties against the disturbances that are associated with a nominal plant model, as it has been developed with the use of the variable structure system (VSS) theory (Utkin, 1992). The crucial part of the control scheme is the asymptotic disturbance estimator. However, as shown in this paper, it fails to stabilise resonant belt dynamics, since it was developed for a rigid robot mechanism. Therefore, this paper introduces an improved motion control scheme, which suppresses the vibrations that would arise due to the non-rigid, elastic drive. Consequently, a rapid response with low position tracking error is guaranteed.The paper is set out as follows. The laser-cutting machine is presented and the control plant model of the machine drives is developed in Section 2. In Section 3, the VSS control regarding the elastic servomechanism is discussed and the derivation of the motion control scheme is described. Section 4 presents the experimental results and a follow-up discussion. The paper is summarized and concluded in Section 5.2. The control plant2.1. The machine descriptionThe laser-cutting machine consists of the XY horizontal table and a laser system (Fig. 1). The fundamental components of the laser system are:● the power supply unit, which is placed off the table and thus is not considered in the motion control design;● the laser-beam source, which generates the laser beam (the laser-generator);●the laser-head, which directs the laser beam onto the desired position in the cutting plane.Fig. 1. The machine and the controller hardware.The table has to move and position the laser head in a horizontal plane. This is achieved by the means of a drive system with two independent motion axes. They provide movement along the Cartesians' XY axes of 2 and 1m, respectively. TheX-drive provides the motion of the laser-head in X-direction. The drive and thelaser-head as well as the laser-generator are placed on the bridge to ensure ahigh-quality optical path for the laser-beam. The movement of the bridge along theY-axis is provided by the Y-drive. The laser-head represents the X-drive load, while the Y-drive is loaded by the bridge, which carries the complete X-drive system, the laser-head, and the laser-generator. The loads slide over the frictionless slide surface.The positioning system consists of the motion controller, the amplifiers, theDC-motors and the drive trains. The X-drive train is composed of a gearbox and a belt-drive (Fig. 2). The gearbox reduces the motor speed, while the belt-drive converts rotary motion into linear motion. The belt-drive consists of a timing belt and of two pulleys: a driving pulley and a driven pulley that stretch the belt. The Y-drive train is more complex. The heavy bridge is driven by two parallel belt-drives; eachbridge-side is connected to one of the belt-drives. The driving pulleys of thebelt-drives are linked to the driving axis, which is driven via the additional belt-drive and the gearbox is used to reduce the speed of the motor.Fig. 2. The drive.2.2. AssumptionsThe machine drives represent a complex non-linear distributed parameter system. The high-order system possesses several resonant frequencies that can be observed by the drives' step response (see Section 4). From a control design perspective, difficulties arise from mechanical vibrations that are met in the desired control bandwidth (~10 Hz). On the other hand, the design objective is to have ahigh-performance control system while simultaneously reducing the complexity of the controller. Therefore, a simple mathematical model would only consider thefirst-order resonance and neglect high-order dynamics. In other words, the design model of the control plant will closely match the frequency response of the real system up to the first resonance. Next, the controller should be adequately designed to cope with the higher-order resonance in such a way that the resonance peaks drop significantly to maintain the system stability. Thus, according to the signal analysis and the drives' features, the following assumptions could be made:●the DC-servos operating in the current control mode ensure a high-dynamic torque response on the motor axis with a negligible time constant;●the small backlash in the gearboxes and the backlash of the belt-drives due to the applied pre-tension of the timing belts is negligible;●a rigid link between a motor shaft and a driving pulley of the belt-drive could be adopted;●the iner tia of the belt-drives' driven pulleys is negligible in comparison to other components of the drive system.Using the assumptions above, dynamic modeling could be reduced to a two-mass model of the belt-drives that only includes the first resonance. In the control design,the uncertain positioning of the load due to the low repeatability and accuracy of the belt-drive has to be considered as well.Note, that no attention is paid to the coupled dynamics of the Y-drive due to the parallel driving, thus, the double belt-drive is considered as an equivalent singlebelt-drive.2.3. The belt-drive modelThe belt-drives could be modelled as a multi-mass system using modal analysis. In the belt-drive model with concentrated parameters, linear, massless springs characterize the elasticity of the belt. According to the assumptions above, a two-mass model can be obtained. The driving-pulley, motor shaft and the speed reducer are considered as the concentrated inertia of the driving actuator. The driven-pulley and the load are concentrated in the load mass. The inertia and the mass are linked by a spring. Friction present in the motor bearings, the gearbox, the belt-drive, andnon-modelled higher-order dynamics are considered as an unknown disturbance that affects the driving side as well as the load side. The mechanical model of thetwo-mass system and its block scheme are shown in Figs. 3 and 4, respectively.The belt-stretch occurs due to the inherent elasticity of the timing belts. However, according to a vibration analysis of belt-drives (Abrate, 1992), the obtained model could be rearranged. Assume the unit transmission constant (L=1). Then, the control plant model is presented by Fig. 5. The control plant consists of two parts connectedin a cascaded structure. The first part is described by poorly damped dynamics due to the elastic belt. The second part consists of the load-side dynamics. The belt-stretch τ forced by the applied torque q. The dynamics are described by Eq. (1)（1）where Hw(s) denotes the belt-stretch dynamics transfer function，（2）and is the natural resonant frequency（3）and is hte disturbance that affects the belt.

The motion control algorithmThe erroneous control model with structured and unstructured uncertainties demands a robust control law. VSS control ensures robust stability for the systems with a non-accurate model, namely, it has been proven in the VSS theory that the closed-loop behavior is determined by selection of a sliding manifold. The goal of the VSS control design is to find a control input so that the motion of the system states is restricted to the sliding manifold. If the system states are restricted to the sliding manifold then the sliding mode occurs. The conventional approach utilises discontinuous switching control to guarantee a sliding motion in the sliding mode. The sliding motion is governed by the reduced order system, which is not affected by system uncertainties. Consequently, the sliding motion is insensitive to disturbance and parameter variations (Utkin, 1992).The essential part of VSS control is its discontinuous control action. In the control of electrical motor drives power switching is normal. In this case, the conventional continuous-time/discontinuous VSS control approach can be successfully applied. However, in many control applications the discontinuous VSS control fails, and chattering arises (S[abanovicH, Jezernik, & Wada, 1996; Young, Utkin & OG zguK ner, 1999). Chattering is an undesirable phenomenon in the control of mechanical systems, since the demanded performance cannot be achieved, or even worse―mechanical parts of the servo system can be destroyed. The main causes of the chattering are neglected high-order control plant dynamics, actuator dynamics, sensor noise, and computer controlled discrete-time implementation in sampled-data systems. Since the main purpose of VSS control is to reject disturbances and to desensitise the system against unknown parametric perturbations, the need to evoke discontinuous feedback control vanishes if the disturbance is sufficiently compensatedfor, e.g. by the use of a disturbance estimator (Jezernik et al., 1994; Kawamura, Itoh& Sakamoto, 1994). Jezernik has developed a control algorithm for a rigid robot mechanism by combining conventional VSS theory and the disturbance estimation approach. However, the rigid body assumption, which neglects the presence of distributed or concentrated elasticity, can make that control input frequencies of the switcher excite neglected resonant modes. Furthermore, in discrete-time systems discontinuous control fails to ensure the sliding mode and has to be replaced by continuous control (Young et al., 1999). Avoiding discontinuous-feedback control issues associated with unmodelled dynamics and related chattering are no longer critical. Chattering becomes a non-issue.In plants where control actuators have limited bandwidth there are two possibilities: actuator bandwidth is outside the required closed-loop bandwidth, or, the desired closed-loop bandwidth is beyond the actuator bandwidth. In the fist case, the actuator dynamics are to be considered as the non-modelled dynamics. Consequently, the sliding mode using discontinuous VSS control cannot occur, because the control plant input is continuous. Therefore, the disturbance estimation approach is preferred rather than VSS disturbance rejection. In the second case, the actuator dynamics are to be lumped together with the plant. The matching conditions (Draz\enovicH, 1969) for disturbance rejection and insensitivity to parameter variations in the sliding mode are violated. This results from having dominant dynamics inserted between the physical input to the plant and the controller output. When unmatched disturbances exist the VSS control cannot guarantee the invariant sliding motion. This restriction may be relaxed by introducing a high-order sliding mode control in which the sliding manifold is chosen so that the associated transfer function has a relative degree larger than one (Fridman& Levant, 1996). Such a control scheme has been used in a number of recently developed VSS control designs, e.g. in Bartolini, Ferrara and Usai (1998). In the latter, the second-order sliding mode control is invoked to create a dynamical controller that eliminates the chattering problem by passing discontinuous control action onto a derivative of the control input.The system to be controlled is given by Eqs. (1) ―(5) and the system output is the load position. The control objective is the position trajectory tracking. The control algorithm that is proposed in this paper has been developed following the idea of the VSS motion control presented by Jezernik. Since the elastic belt-drive behaves as alow bandwidth actuator, the conventional VSS control algorithm failed to achieve the prescribed control objective. Thus, the robust position trajectory tracking control algorithm presented in the paper has been derived using second-order sliding mode control. In order to eliminate the chattering problem and preserve robustness, the control algorithm uses the continuous control law. Following the VSS disturbance estimation approach, it will be shown that the disturbance estimation feature of the proposed motion control algorithm is similar to the control approach of Jezernik (Jezernik et al., 1994). Additionally, the proposed control algorithm considers the actuator dynamics in order to reshape the poorly damped actuator bandwidth. Consequently, the proposed motion controller consists of a robust position-tracking controller in the outer loop and a vibration controller in the inner loop (Fig. 6). This section is organized as follows. Section 3.1 presents the proposed VSS control design.Section 3.2 describes the derivation of the robust position controller.Section 3.3 provides a description of the vibration controller. Finally, the proposed control scheme is described in Section 3.4.激光切割机的传动控制可变结构系统艾力斯•霍斯，卡瑞尔•诘责尼克，马丁•特布马里博尔大学机器人学学院电气工程系和计算机科学系截稿于1999年10月18日，出版与2000年6月2日.内容摘要﹕一种先进的位置跟踪控制算法已经研制出来了，并将其应用在激光切割机的数控运动控制器上。
