	LABTM control system based on FPGA (EI CONFERENCE) 会议论文 OAI收割 2nd International Conference on Mechatronics and Applied Mechanics, ICMAM 2012, December 8, 2012 - December 9, 2012, Taiwan 作者: Wang Y.; Yu P.; Yu P.; Wang Y.; Wang Y. 收藏 \| 浏览/下载：153/0 \| 提交时间：2013/03/25 This paper presents the digital PI control method for design and simulation of a high precision limited angle brushless torque motor control system in Field Programmable Gate Array device (FPGA). The direct drive structures which are widely applied in many servo control fields. Matlab Xilinx System GeneratorR toolbox based on Fixed-Point Arithmetic is used to design the digital PI controller using DSP architecture plot the responses of the control system and generate the VHDL source code. The control system model consists of a digital PI a real LABTM and a real absolute Inductosyn encoder to rpm and position blocks. Through loading generated codes in process of the simulation that built by the digital discrete model it is verified that the rising time of current loop is only 1.2ms and rate loop is 8ms overshoot is rarely 4.2%. Finally the comprehensive positioning accuracy of system can reach up to 5 arc sec and the rate jitter achieves 5% with the 4 arc sec accuracy absolute Inductosyn.

	Study of high precision non-contact measurement based on CCD (EI CONFERENCE) 会议论文 OAI收割 4th International Conference on Information Technology and Applications, ICITA 2007, January 15, 2007 - January 18, 2007, Harbin, China Lin L.; Yun F. 收藏 \| 浏览/下载：22/0 \| 提交时间：2013/03/25 In this paper a method that measures relatively positionrelationshipquickly and accurately between two vehicles both on a horizontal plane is introduced. When the linear CCD camera placed on the end of manipulator scans two point targets located on the other vehicle by virtue of the spatial intersection principle and trigonometry theorem the relative position relationship between the loading vehicles and launching ones can be gotten(i.e. the spatial coordinate parameters of x y z and the angle displacement ). At the same time the paper establishes that the measurement error of length is less than 1mm by analysis of thee rror analysis and the simulation of computer. The angle displacement is less than 3 which satisfies the technical requests. So the vehicle orientation and loading missiles can be both done at the shortest time. It meets the demand of centralization between the measurement and execution. Forboth automatic transshipment and spatial position relationship measurement the study is valuable. And the manipulator is measure device as well as executive one so that residual inherent error decreases according to identical reference principle. Therefore the measure precision can be improved greatly.

	Application of linear CCD for position measurement (EI CONFERENCE) 会议论文 OAI收割 ICO20: Optical Devices and Instruments, August 21, 2005 - August 26, 2005, Changchun, China 作者: Fu Y.; Liu L.; Liu L. 收藏 \| 浏览/下载：26/0 \| 提交时间：2013/03/25 A method that measures relatively position relation between two vehicles fleetly and accurately that are both on a horizontal plane is proposed in the article. When manipulator rotates horizontally that of angle is less than 26 the linear CCD vidicon that is on the end of manipulator on the loading vehicle scans two point targets that are on the launching vehicle which satisfies technical requests. So the method is feasible. The research is not only significant for missile of automatic transshipment and then we can utilize spatial intersection principle and trigonometry theorem to get relatively position relationship. I.e. the coordinate parameters: x but also is valuable in theoretic research on method of measuring spatial position relationship. y z . Error analysis and the simulation on computer validate: the measurement error of length is less than 0.84mm
