改进型自适应无迹卡尔曼姿态算法
改进型自适应无迹卡尔曼姿态算法侯江宽;马珺;贾华宇【摘要】提出了一种改进型自适应无迹卡尔曼滤波姿态算法,能够有效的解决MEMS陀螺仪的漂移和噪声问题,同时减小运动加速度对加速度计的影响.将改进的自适应Sage-Husa算法与无迹卡尔曼滤波器相结合,使量测噪声统计特性在线更新,提高系统的抗干扰能力,避免扩展卡尔曼滤波的线性化误差,可以得到精确的全姿态角.每次迭代只更新3个欧拉角,提高了系统的解算速度.飞行实验和分析表明:改进算法能够有效的提高姿态解算精度,收敛速度快,自适应能力强,稳定可靠,具有较强的鲁棒性,在干扰消失时能够快速得到准确姿态角.%An improved adaptive unscented Kalman filter for attitude determination is proposed, which can effectively solve the drift and noise problem of gyroscope and reduce the influence of motion acceleration on the ac-celerometer. Combining the improved adaptive Sage-Husa algorithm with the unscented Kalman filter,the statistic characteristic of the measurement noise is updated on-line,the anti-jamming capability of the system is improved, and the linearization error of the extended Kalman filter can be avoided. And we can get the precise Attitude angle. Only three Euler angles are updated each iteration which can improve the solution speed of the system. The flight experiment and analysis show that the improved algorithm can effectively improve the accuracy of attitude determi-nation,improve convergence speed,strong adaptability,robustness and stability,and can get the accurate attitude an-gle quickly when the interference disappears.【期刊名称】《传感技术学报》【年(卷),期】2017(030)010【总页数】7页(P1518-1524)【关键词】传感器;姿态解算;无迹卡尔曼滤波器;自适应Sage-Husa算法;多旋翼飞行器【作者】侯江宽;马珺;贾华宇【作者单位】太原理工大学物理与光电工程学院,山西晋中030600;太原理工大学物理与光电工程学院,山西晋中030600;太原理工大学信息工程学院,山西晋中030600【正文语种】中文【中图分类】TP27获取准确的姿态是无人飞行器实现自主飞行的前提条件[1],由于MEMS(Micro Electro Mechanical Systems)传感器的高集成度、低成本,在微型飞行器上大量使用。
高中英语选择性必修一第一单元作业
4-1课时作业Ⅰ.阅读理解A(2021·福州模拟)When Millet was a boy he worked on his needy father's farm. At the rest hour in the fields the other workers would all take naps, but young Millet would spend time drawing.Finally the village where he lived gave him a little money to Paris to study art.When Millet reached Paris he had a tough time.Fortunately, when he was almost starving someone bought one of his peasant paintings, which enabled his family to leave for Barbizon.Millet's pictures of peasants at work were painted in a unique way. The painter would go out on the farms and watch them carefully—digging, hoeing, spreading manure, sawing wood, or sowing grain. Then he would come home and paint what he had seen. So astonishingly accurate was his memory that he could paint at home without models and get all the movements of his figures right. When he did need a figure to go by he would ask his wife to pose for him.One of his noted artworks is called “The Sower”，which shows a man seeding. He reaches into his bag for seed and then swings backward to scatter the seed, and with each swing of his hand the sower strides forward. In Millet's picture the sower has been working hard, but his swinging step and arm still move smoothly, like a machine. Only the man's head reveals his great tiredness.Another m asterpiece is called “The Gleaners”. A gleaner is someone picking up the leftover in the field after the wheat harvest.When farmers near Barbizon are extremely badly-off, even the little the gleaners can find is a help. You can see from Millet's picture what back-breaking work gleaning must be.1．What do we know about Millet?A．His wife supported him to be a painter.B．He was keen on painting as a kid.C．He spent his whole life in Barbizon.D．He was brought up in Paris.2．How did he paint the laboring farmers?A．Asking models for help.B．Imagining figures in the field.C．Remembering what he had observed.D．Recalling the days on his father's farm.3．What do Millet's works convey?A．The farmers' hardships.B．The scene of farming.C．His love for the village.D．His anxiety about the farmers.4．What painting style of Millet can be inferred from the text?A．Impressionistic.B．Abstract.C．Romantic. D. Realistic.【语篇解读】本文主要介绍了著名画家Millet从小就喜欢画画，他的画作主要描绘了农民劳动时的场景。

It isimportant that you read and understand this manual prior to beginning the installation.If at any time during the installation you should have any questions, contact Newall or your local authorised representative.1.1BracketsDue to the variety of machine types and applications, it may be necessary to design, make and fit custom bracketsfor the encoder assembly. If brackets are needed, make certain they are rigid enough to prevent any flexing ordistorting while the machine is in operation. Newall offers a variety of bracket kits to aid in the installation.Contact Newall or your local authorised representative for details.1.2PreparationPrior to beginning the installation the machine should be studied to determine where the encoder(s) will be fitted.For best results, it is recommended that the encoder be fitted as close to the machine lead screw or axial driveshaft as possible.DSG: Overall Length = T ravel + 258mm (10.2”)DMG: Overall Length = T ravel + 187mm (7.4”)Outboard mounting of the scale support brackets will add approximately 20mm (3/4") to the stated travel. (Referto Section 10.0)For a more compact installation, scale travels of 300mm (12") or less may be fitted by supporting one end of thescale only by use of a single end mounting block. (Refer to Figure 6.4 and 6.10)It is prefered the moving member of the encoder assembly is the reader head; the scale can be the movingmember but only on certain applications.Cable routing from the reader head should be examined (see section 7). Extension cables are available in a varietyof lengths. Contact Newall or your local authorised representative for further details.For encoders larger than 1500mm (60”) travel, a setup tube (blank scale) is recommended.1.3WarningsIf for any reason the machine axis travel is greater than the actual scale travel it is recommended that mechanicalstops are fitted to the machine to avoid damage caused by over-travel. Newall will not accept responsibility forscale and reader head damage caused by machine over-travel.Both the reader head and the scale are precision made components and it is important that they are handled withcare. By design the encoders can withstand the rigours of the harsh workshop environment. However, permanent damage can occur through bending or severe impact.It is important that the scale be kept at least 13mm (0.5") away from any magnetic bases on indicators or magnetic chucks.DSG and DMG encoders are designed to operate with Digital Readout Systems and therefore may not operatecorrectly with automated or closed loop motion control systems.

(Refer to Figure 5.2)newall Measurement systemsnotes:Erroneous readings will occur if the reader head is allowed to travel beyond the effective travel limits. (Refer to Figure 6.1)The pre-load on the balls are factory set via the set screw at the tensioner end. Do not tamper with or adjust the set screw as this will alter the calibration and accuracy specification of the scale. (Refer to Figure 6.1)Once the reader head is secured and correctly aligned, the scale support brackets can now be fitted. The scale support brackets consist of the support pin, the support link and the pillar(s).raverse the machine to its maximum position toward the non-cable entry side of the reader head. Maximum position means all available travel, including hand winding past any electrical limits or trip dogs.Carefully slide the blank scale (or DSG scale if less than 1500mm (60") travel), allowing for a sufficient amount of scale to project from the reader head in order to fit the scale support brackets.Assemble the scale support link to the scale support pin leaving approximately 3mm (1/8") gap between the bottom of the pin shoulder and the top of the link.Slide the link/pin assembly onto the scale to approximately 5mm (0.2") away from the end of the reader head.

While gently sliding the scale forward and back 25 - 50mm (1" - 2") through the support pin, carefully tighten the hex screws on the support link, ensuring that the scale slides smoothly through the reader head and into the support pin. If any interference is detected then fully loosen the hex screws on the support link and repeat this step.Repeat the above steps at the other end of the machine. Then carefully slide the DSG Scale through the support pin,through the reader head and into the opposite support pin. Tighten the hex screws on the anchor pins.6.1.2single end Mounting note: the maximum total length of the scale must not exceed 610mm (24") when using a singleend mounting kit. the single end mounting kit is sold separately, ask for part number600-63610.Remove the white rivet from the fixed end of the scale, by prying out with a straight edge screwdriver/tool.After the reader head has been installed slide the scale through the reader head and insert the fixed end of the scale into the single end mounting block. (Refer to Figure 6.4)Once the position for the single end mounting block has been determined mark the machine casting using the slot in the mounting block as the guide . Drill and tap M6 x 12mm deep. Fit the mounting block using the M6 socket head cap screw and washer.Check the alignment by gently sliding the scale through the head and in and out of the mounting block, adjustments may be carried out by altering the M5 jacking screws.

Dangling and loose cables can be snagged or broken causing irreparable damage. Care should be taken in order to ensure that the cables are secured to the machine and that cable loops do not interfere with any part of the machine or the encoder movements. "P" clips and thread forming screws are provided to route the cables.note: the armoured cable is an integral part of the reader head. If the cable becomes damaged,then it would have to be replaced complete with the reader head.If extension cables are used, do not allow the plug and socket junction to lie in the swarf tray or in the direct flow of coolant or oil.In order to avoid problems associated with electrical noise and interference, do not allow the cables to lie across electrical motors, fuse boxes or electrical pumps.9.0FInAL CHeCkPrior to putting the encoder into operation, slowly traverse the machine axis to both extents of its travel checking at all times that the cables are secure and that machine over travel cannot occur.

The driver, as seen by the European Commission:
The large scale adoption of smart metering is today hampered by the lack of widely accepted open standards capable of guaranteeing interoperability of systems and devices produced by different manufacturers
Official Journal of the European Union
The OPEN meter project is an official initiative by the European Commission
