附录2：英文资料及其中文翻译Stepper motor is an electrical pulse will be converted into angular displacement of the implem enting agencies. Put it in simple language-speaking: When the stepper drive pulse signal to a r eceiver, it drives stepper motor rotation direction by setting a fixed point of view (and the ste p angle). You can control the number of pulses to control the amount of angular displacement, so as to achieve the purpose of accurate positioning; At the same time, you can by controllin g the pulse frequency to control the motor rotation speed and acceleration, so as to achieve th e purpose of speed.Stepper motor directly from the AC-DC power supply, and must use special equipment - stepp er motor drive. Stepper motor drive system performance, in addition to their own performance with the motor on the outside, but also to a large extent depend on the drive is good or bad.A typical stepper motor drive system is operated by the stepper motor controller, stepper mot or drives and stepper motor body is composed of three parts. Stepper motor controller stepper pulse and direction signal, each made of a pulse, stepper motor-driven stepper motor drives a rotor rotating step angle, that is, step-by-step further. High or low speed stepper motor, or spe ed, or deceleration, start or stop pulses are entirely dependent on whether the level or frequenc y. Decide the direction of the signal controller stepper motor clockwise or counterclockwise rot ation. Typically, the stepper motor drive circuit from the logic control, power driver circuit, pr otection circuit and power components. Stepper motor drive controller, once received from the direction of the signal and step pulse, the control circuit on a pre-determined way of the electr ical power-phase stepper motor excitation windings of the conduction or cut-off signal. Control circuit output signal power is low, can not provide the necessary stepping motor output powe r, the need for power amplifier, which is stepper motor driven power drive part. Power stepper motor drive circuit to control the input current winding to form a space for rotating magnetic field excitation, the rotor-driven movement. Protection circuit in the event of short circuit, ove rload, overheating, such as failure to stop the rapid drive and motor.Motor is usually for the permanent magnet rotor, when the current flows through the stator wi ndings, the stator windings produce a magnetic field vector. The magnetic field will lead to a rotor angle of rotation, making a pair of rotor and stator magnetic field direction of the magne tic field direction. When the stator rotating magnetic field vector from a different angle. Also as the rotor magnetic field to a point of view. An electrical pulse for each input, the motor r otation angle step. Its output and input of the angular displacement is proportional to the pulse s, with pulse frequency proportional to speed. Power to change the order of winding, the elect rical will be reversed. We can, therefore, control the pulse number, frequency and electrical po wer windings of each phase to control the order of rotation of stepper motor.Stepper motor types:Permanent magnet (PM). Magnetic generally two-phase stepper, torque and are smaller and gen erally stepping angle of 7.5 degrees or 15 degrees; put more wind for air-conditioning. Reactive (VR), the domestic general called BF, have a common three-phase reaction, step angl e of 1.5 degrees; also have five-phase reaction. Noise, no torque has been set at a large numb er of out.Hybrid (HB), common two-phase hybrid, five-phase hybrid, three-phase hybrid, four-phase hybri d, two-phase can be common with the four-phase drive, five-phase three-phase must be used w ith their drives;Two-phase, four-phase hybrid step angle is 1.8 degrees more than a small size, great distance, and low noise;Five-phase hybrid stepping motor is generally 0.72, the motor step angle small, high resolution, but the complexity of drive circuits, wiring problems, such as the 5-phase system of 10 lines. Three-phase hybrid stepping motor step angle of 1.2 degrees, but according to the use of 1.8 degrees, the three-phase hybrid stepping motor has a two-phase mixed than the five-phase hybr id more pole will help electric folder symmetric angle, it can be more than two-phase, five-ph ase high accuracy, the error even smaller, run more smoothly.Stepper motor to maintain torque: stepper motor power means no rotation, the stator locked rot or torque. It is a stepper motor, one of the most important parameters, usually in the low-spee d stepper motor torque at the time of close to maintain the torque. As the stepper motor outp ut torque increases with the speed of constant attenuation, the output power also increases with the speed of change, so as to maintain torque on the stepper motor to measure the parameter s of one of the most important. For example, when people say that the stepper motor 2N.m, i n the absence of special circumstances that means for maintaining the torque of the stepper m otor 2N.m.Precision stepper motors: stepper motor step angle accuracy of 3-5%, not cumulative.Start frequency of no-load: the stepper motor in case of no-load to the normal start of the pul se frequency, if the pulse frequency is higher than the value of motor does not start, possible to lose steps or blocking. In the case of the load, start frequency should be lower. If you wa nt to achieve high-speed rotation motor, pulse frequency should be to accelerate the process, th at is, the lower frequency to start, and then rose to a certain acceleration of the desired freque ncy (motor speed from low rise to high-speed).Step angle: that is to send a pulse, the electrical angle corresponding to rotation.Torque positioning: positioning torque stepper motor does not refer to the case of electricity, l ocked rotor torque stator.Operating frequency: step-by-step stepper motor can run without losing the highest frequency. Subdivision Drive: stepper motor drives the main aim is to weaken or eliminate low-frequency vibration of the stepper motor to improve the accuracy of the motor running. Reduce noise. I f the step angle is 1.8 °(full step) the two-phase hybrid stepping motor, if the breakdown of the breakdown of the number of drives for the 8, then the operation of the electrical pulse for each resolution of 0.072 °, the precision of motor can reach or close to 0.225 °, also depend s on the breakdown of the breakdown of the drive current control accuracy and other factors, the breakdown of the number of the more difficult the greater the precision of control.步进电机是一种将电脉冲转化为角位移的执行机构。

Say all:Along with the micro-electronics technique and the calculator technical hair Exhibition, the programmable preface controller has an advance by leaps and bounds of hair Exhibition, its function has already outrun a logic control far and far, in proper order The scope of control, it has an effect to combine with calculator, can enter Go to imitate to control most, have along range correspondence function etc.. Have-The person is called it the modern D industry controls of three pay pillar greatly(namely PLC, robot, CAD/CAM)it a, currently programmable controller BE applied in metallurgy extensively, Mineral industry, machine, light Class D realm, automate for the industry Provided to there is the tool of one dint The PLC controls of tread to open the wreath servo organization into the electrical engineering should Used for combining tool machine to produce an on-line number to control a slippery pedestal to control automatically Make, can the province go to the number of that unit to control system, making that unit The cost of controlling the system lowers.2、What is a stepper motor：Stepper motor is a kind of electrical pulses into angular displacement ofthe implementing agency. Popular little lesson: When the driver receives a step pulse signal, it will drive a stepper motor toset the direction of rotation at a fixed angle (and the step angle). You can control the number of pulses to control the angular displacement, so as to achieve accurate positioning purposes; the same time you can control the pulse frequency to control the motor rotation speed and acceleration, to achieve speed control purposes.What kinds of stepper motor sub-：In three stepper motors: permanent magnet (PM), reactive (VR) and hybrid (HB) permanent magnet stepper usually two-phase, torque, and smaller, step angle of 7.5 degrees or the general 15 degrees; reaction step is generallythree-phase, can achieve high torque output, step angle of 1.5 degrees is generally, but the noise and vibration are large. 80 countries in Europe and America have been eliminated; hybrid stepper is a mix of permanent magnet and reactive advantages. It consists of two phases and the five-phase: two-phase step angle of 1.8 degrees while the general five-phase step angle of 0.72 degrees generally. The most widely used Stepper Motor. What is to keep the torque (HOLDING TORQUE)3、Tread into the basic characteristics of electrical engineering:（1）、tread generally into the accuracy of the electrical engineering for tread into Cape of 3-5% and don't accumulate.（2）、tallest temperatures which enter electrical engineering outward appearance and allow tread and lead into the electrical engineering temperature high can make the magnetism material of electrical engineering back first, cause the dint descend thus is as for lose a step, so the electrical engineering outward appearance allow of the tallest temperature should be decided by small back with electrical engineeringmagnetism material and order; Speak generally, the magnetism material backs to order all above have in 130 C an of even be up to 200C above, so tread completely normal into the electrical engineering outward appearance temperature in 80-90C.（3）、dints which enter electrical engineering would with turn to go up but descend soon，While treading to turn to move into the electrical engineering,electrical engineering each electricity feeling which round a set mutually will become one anti- to electromotive force; The frequency is more high, anti- to electromotive force more big ，big in its function, the electrical engineering enlarges with the frequency(or speed) but mutually the electric current let up, causing the dint descend thus.（4）、can revolve normally when 4 enter electrical engineering low speed, but if high in certain the speed can't start, and the companion have a roar the interjection tread to have a technique parameter into the electrical engineering: empty carry start frequency, then tread into electrical engineering at empty carry under circumstance can start normally of pulse frequency, if the pulse frequency is high in should be worth., The electrical engineering can't start normally, the possible occurrence throws a step or blocks up to turn. Under the situation that there is one load, the start frequency should be much lower if want to make the electrical engineering attain high speed to turn to move, the pulse frequency should have an acceleration process, then start the frequency is lower, then press certain acceleration to rise the high hoped. Tread to show the characteristics of with it into the electric motor, turn ages of manufacturing to develop important use to accompany with in the numeral small together of numeral turn technical of development and tread into the electricalengineering technical exaltation，tread will get an application in more realms into the electrical engineering.4、enter an electrical engineering control system to constitute：Tread is a kind of performance organization that will give or get an electric shock a pulse conversion to move for the Cape into the electrical engineering. When tread to receive to a pulse signal into the actuator, it drives a step to press the direction of enactment to turn to move an angle for fixing to be called "tread to be apart from Cape" into the electrical engineering, it revolves one-step circulate with the fixed angle one step. Can pass control pulse piece to control a Cape to move to attain the purpose of assurance most and thus; Can pass control pulse frequency to control electrical engineering to become dynamic speed and acceleration in the meantime, the purpose attained to adjust thus soon treads into the electrical engineering. Can be the special kind electrical engineering that a kind of control uses, make use of it didn't accumulate error margin accuracy to 100 to divide 100 of characteristics, be suffused with to apply in various open a wreath control PLC which enter electrical engineering technique.5、Stepper motor of the PLC control technology:Make the importation tread to be subjected to a homologous control into total amount and pulse frequency of the importation pulse of electrical engineering. Establish the pulse signal occurrence that a pulse total amount and pulse frequency can control a machine therefore and in control，software; Can make use of PL in fixed time a machine composing for the frequency lower control pulse, the pulse frequency can pass in fixed time machine in fixed time constant control pulse period, the pulse amounts control then can establish a the pulsecounter C10 be when the pulse number attain initial value, count machine C1.The action cuts off pulse back track, making it stop, the servo organization tread into the electrical engineering have no the pulse input then stop operation，servo performance organization fixed position be servo performance organization of when move speed to have higher request, can use PLC high-speed pulse，Different PLC it the frequency of high-speed pulse can reach to 4000-6000Hzses. The PLC is used to produce control pulse, passing PLC plait distance exportation several pulses certainly the control treads to turn Cape into the electrical engineering, programmable controller output's control the pulse enters electrical engineering to switch on electricity sequence to assign by the step homologous of round a set. The PLC controls of tread can go an allotment machine by adoption software wreath into the electrical engineering, the hardware wreath goes allotment machine to adopt the PLC resources that the soft wreath takes up more, Tread especially to round a set to count mutually into the electrical engineering big should consider adoption hardware wreath to go allotment machine well for large production line at 4, although the hardware structure is a little bit a little more complicated, can save an exportation importation of taking up the PLC point, the market has a various appropriation chips to choose to use currently. Tread to enlarge to several ten highest hundred folds into the output's control of the actuator PLC of the electrical engineering power pulse, volt, several Anne arrive several ten several Anne s drive an ability, the exportation of general PLC connects to have to certainly drive an ability, but inside usual transistor flow exportation to connect an ability only for ten several arrive several ten volts, several ten arrive several 100 million Anne but tread to then have several request into theelectrical engineering to the power ten arrive up 100 volts, several Anne arrive several ten Anne s drive an ability so should adopt an actuator to output the pulse carry on enlarging.6、Application features of PLC（1）、High reliability, strong anti-interferenceHigh reliability is the key to performance of electrical control equipment.

步进电机的振荡、不稳定以及控制摘要：本文介绍了一种分析永磁步进电机不稳定性的新颖方法。

结果表明，该种电机有两种类型的不稳定现象：中频振荡和高频不稳定性。

非线性分叉理论是用来说明局部不稳定和中频振荡运动之间的关系。

一种新型的分析介绍了被确定为高频不稳定性的同步损耗现象。

在相间分界线和吸引子的概念被用于导出数量来评估高频不稳定性。

通过使用这个数量就可以很容易地估计高频供应的稳定性。

此外，还介绍了稳定性理论。

广义的方法给出了基于反馈理论的稳定问题的分析。

结果表明，中频稳定度和高频稳定度可以提高状态反馈。

关键词：步进电机，不稳定，非线性，状态反馈。

1. 介绍步进电机是将数字脉冲输入转换为模拟角度输出的电磁增量运动装置。

其内在的步进能力允许没有反馈的精确位置控制。

也就是说，他们可以在开环模式下跟踪任何步阶位置，因此执行位置控制是不需要任何反馈的。

步进电机提供比直流电机每单位更高的峰值扭矩;此外，它们是无电刷电机，因此需要较少的维护。

所有这些特性使得步进电机在许多位置和速度控制系统的选择中非常具有吸引力，例如如在计算机硬盘驱动器和打印机，代理表，机器人中的应用等.尽管步进电机有许多突出的特性，他们仍遭受振荡或不稳定现象。

这种现象严重地限制其开环的动态性能和需要高速运作的适用领域。

这种振荡通常在步进率低于1000脉冲/秒的时候发生，并已被确认为中频不稳定或局部不稳定[1]，或者动态不稳定[2]。

此外，步进电机还有另一种不稳定现象，也就是在步进率较高时，即使负荷扭矩小于其牵出扭矩，电动机也常常不同步。

该文中将这种现象确定为高频不稳定性，因为它以比在中频振荡现象中发生的频率更高的频率出现。

高频不稳定性不像中频不稳定性那样被广泛接受，而且还没有一个方法来评估它。

中频振荡已经被广泛地认识了很长一段时间，但是，一个完整的了解还没有牢固确立。

这可以归因于支配振荡现象的非线性是相当困难处理的。

大多数研究人员在线性模型基础上分析它[1]。

在没有脉冲输入时，在绕组电源的激励下气隙磁场能使转子保持原有位置处于定位状态。

因此非常适合于单片机控制。

步进电机还具有快速启动、精确步进和定位等特点，因而在数控机床，绘图仪，打印机以及光学仪器中得到广泛的应用。

步进电动机已成为除直流电动机和交流电动机以外的第三类电动机。

传统电动机作为机电能量转换装置，在人类的生产和生活进入电气化过程中起着关键的作用。

步进电机可以作为一种控制用的特种电机，利用其没有积累误差(精度为100%)的特点，广泛应用于各种开环控制。

现在比较常用的步进电机包括反应式步进电机（VR）、永磁式步进电机（PM）、混合式步进电机（HB）和单相式步进电机等。

一步进电机的工作原理步进电机是一种用电脉冲进行控制 ,将电脉冲信号转换成相位移的电机 ,其机械位移和转速分别与输入电机绕组的脉冲个数和脉冲频率成正比 ,每一个脉冲信号可使步进电机旋转一个固定的角度.脉冲的数量决定了旋转的总角度 ,脉冲的频率决定了电机运转的速度.当步进驱动器接收到一个脉冲信号，它就驱动步进电机按设定的方向转动一个固定的角度(称为“步距角”)，它的旋转是以固定的角度一步一步运行的。

可以通过控制脉冲个数来控制角位移量，从而达到准确定位的目的；同时可以通过控制脉冲频率来控制电机转动的速度和加速度，从而达到调速的目的。

二步进电机详细调速原理步进电机的调速一般是改变输入步进电机的脉冲的频率来实现步进电机的调速，因为步进电机每给一个脉冲就转动一个固定的角度，这样就可以通过控制步进电机的一个脉冲到下一个脉冲的时间间隔来改变脉冲的频率，延时的长短来具体控制步进角来改变电机的转速，从而实现步进电的调速。

Knowledge of the stepper motorWhat is a stepper motor：Stepper motor is a kind of electrical pulses into angular displacement of the implementing agency. Popular little lesson: When the driver receives a step pulse signal, it will drive a stepper motor to set the direction of rotation at a fixed angle (and the step angle). You can control the number of pulses to control the angular displacement, so as to achieve accurate positioning purposes; the same time you can control the pulse frequency to control the motor rotation speed and acceleration, to achieve speed control purposes.What kinds of stepper motor sub-：In three stepper motors: permanent magnet (PM), reactive (VR) and hybrid (HB) permanent magnet stepper usually two-phase, torque, and smaller, step angle of 7.5 degrees or the general 15 degrees; reaction step is generally three-phase, can achieve high torque output, step angle of 1.5 degrees is generally, but the noise and vibration are large. 80 countries in Europe and America have been eliminated; hybrid stepper is a mix of permanent magnet and reactive advantages. It consists of two phases and the five-phase: two-phase step angle of 1.8 degrees while the general five-phase step angle of 0.72 degrees generally. The most widely used Stepper Motor.What is to keep the torque (HOLDING TORQUE)How much precision stepper motor? Whether the cumulative：The general accuracy of the stepper motor step angle of 3-5%, and not cumulative. Stepper motor to allow the minimum amount of surface temperatureStepper motor to allow the minimum amount of surface temperature：Stepper motor causes the motor temperature is too high the first magnetic demagnetization, resulting in loss of torque down even further, so the motor surface temperature should be the maximum allowed depending on the motor demagnetization of magnetic material points; Generally speaking, the magnetic demagnetization points are above 130 degrees Celsius, and some even as high as 200 degrees Celsius, so the stepper motor surface temperature of 80-90 degrees Celsius isnormal.How to determine the stepper motor driver DC power supply：A. Determination of the voltageHybrid stepping motor driver power supply voltage is generally a wide range (such as the IM483 supply voltage of 12 ~ 48VDC), the supply voltage is usually based on the work of the motor speed and response to the request to choose. If the motor operating speed higher or faster response to the request, then the voltage value is high, but note that the ripple voltage can not exceed the maximum input voltage of the drive, or it may damage the drive.B. Determination of CurrentPower supply current is generally based on the output phase current drive I to determine. If a linear power supply, power supply current is generally preferable 1.1 to 1.3 times the I; if we adopt the switching power supply, power supply current is generally preferable to I, 1.5 to 2.0 times.The main characteristics of stepping motor：A stepper motor drive can be added operate pulse drive signal must be no pulse when the stepper motor at rest, such asIf adding the appropriate pulse signal, it will to a certain angle (called the step angle) rotation. Rotation speed and pulse frequency is proportional to.2 Dragon step angle stepper motor version is 7.5 degrees, 360 degrees around, takes 48 pulses to complete.3 stepper motor has instant start and rapid cessation of superior characteristics. Change the pulse of the order of 4, you can easily change the direction of rotation. Therefore, the current printers, plotters, robotics, and so devices are the core of the stepper motor as the driving force.Stepper motor control exampleWe use four-phase unipolar stepper motor as an example. The structure shown in Figure 1:Four four-phase winding leads (as opposed to phase A1 A2 B1 phase phase B2) and two public lines (to the power of positive). The windings of one phase to thepower of the ground. So that the windings will be inspired. We use four-phase eight-beat control, ie, 1 phase 2 phase alternating turn, would enhance resolution.0.9 ° per step can be transferred to control the motor excitation is transferred in order as follows:If the requirements of motor reversal, the transmission excitation signal can be reversed. 2 control schemeControl system block diagram is as followsThe program uses AT89S51 as the main control device. It is compatible with the AT89C51, but also increased the SPI interface and the watchdog module, which not only makes the debugging process becomes easy and also more stable. The microcontroller in the program mainly for field signal acquisition and operation of the stepper motor to calculate the direction and speed information. Then sent to the CPLD. CPLD with EPM7128SLC84-15, EPM7128 programmable logic device of large-scale, for the ALTERA company's MAX7000 family. High impedance, electrically erasable and other characteristics, can be used for the 2500 unit, the working voltage of +5 V. CPLD receives information sent from the microcontroller after converted to the corresponding control signal output to the stepper motor drive. Put the control signal drives the motor windings after the input, to achieve effective control of the motor.2.1 The hardware structure of the motor driveMotor drive using the following circuit:R1-R8 in which the resistance value of 320Ω. R9-R12 resistance value 2.2KΩ. Q1-Q4 as Darlington D401A, Q5-Q8 for the S8550. J1, J2 and the stepper motor connected to the six-lead。

步进电机及其驱动系统简介中英文翻译 Step characteristics for machine for angular displacement for entering the electrical engineering is first kind will give or get an electric shocking the pulse signal conversion cowgirl or line potential moving battery carry outing a piece, having the fast stopping, accurate step entering and directly accepting the arithmetic figure measuring, because of but got the extensive application.Such as in the drafting machine, print the machine and optical instrument inside, and all adopt the inside of a place control system for entering the electrical engineering to positioning to paint the pen print head or optical prinipal, especially indrstry process the type control, and move to spread to feel the to can immediately attain the precision fixed position because of its precision and need not potential, and control the technique along with the calculator of continuously deveolp, applied to would be more and more extensive. Control and can is divided into the simple control sum the complicacy to control to motor two kind.The simple control points to proceeds to start to motor, the system move, positive and negative revolution and sequential control.Complicacy the control point to the motor's revolving speed, screw angle, turning moment, tension, electric current etc. physics quantisty progress control.Control technique that the development that motor get force is in latest development achievement that micro-electronics technique, electric power electronics, spread to feel the the technique, automatic control the technique, tiny machine the application technique to wait.Exactly the advance of these techniques make the motor control the technique at near two 10-year insides change for turn overing the ground of day is take placed.Among them the motor's control division have already been controled by emulation gradually let locate to regard single flake machine as principle of microprocessor control, formation the mix control system of the arithmetic figure and emulation and the application of the pure arithmetic figure control system, combine control the direction to total amount word to quickly deveolp.The motor's drive part of power for using the piece experienced a few renewals 1 to change the on behalf, current switch speed sooner, more simple whole type power piece of control the MOSFET become the main current with IGBT. Stepper motors have the following benefits: • Low cost • Ruggedness • Simplicity in construction • High reliability • No maintenance • Wide acceptance • No tweaking to stabilize • No feedback components are needed • They work in just about any environment • Inherently more failsafe than servo motors. There is virtually no conceivable failure within the stepper drive module that could cause the motor to run away. Stepper motors are simple to drive and control in an open-loop configuration. They only require four leads. They provide excellent torque at low speeds, up to 5 times the continuous torque of a brush motor of the same frame size or double the torque of the equivalent brushless motor. This often eliminates the need for a gearbox. A stepper-driven-system is inherently stiff, with known limits to the dynamic position error. Stepper Motor Disadvantages Stepper motors have the following disadvantages: • Resonance effects and relatively long settling times • Rough performance at low speed unless a microstep drive is used • Liability to undetected position loss as a result of operating open-loop • They consume current regardless of load conditions and therefore tend to run hot • Losses at speed are relatively high and can cause excessive heating, and they are frequently noisy (especially at high speeds). 2 • They can exhibit lag-lead oscillation, which is difficult to damp. There is a limit to their available size, and positioning accuracy relies on the mechanics (e.g., ballscrew accuracy). Many of these drawbacks can be overcome by the use of a closed-loop control scheme. Note: The Compumotor Zeta Series minimizes or reduces many of these different stepper motor disadvantages. There are three main stepper motor types: • Permanent Magnet (P.M.) Motors • Variable Reluctance (V.R.) Motors • Hybrid Motors When the motor is driven in its full-step mode, energizing two windings or “phases” at a time (see Fig. 1.8), the torque available on
