	Design of control system of DC motor based on fusion FPGA (EI CONFERENCE) 会议论文 OAI收割 2011 International Conference on Mechatronics and Materials Processing, ICMMP 2011, November 18, 2011 - November 20, 2011, Guangzhou, China Zhu D. D.; Li H. W. 收藏 \| 浏览/下载：38/0 \| 提交时间：2013/03/25 Along with the development of microelectronic process it is possible to integrate a big system in one chip. A new way to implement system on a chip is provided by the advent of FPGA. Based on Verilog HDL and the Actel Fusion AFS600 FPGA chip the speed closed-loop control system of DC motor was designed by using options of combining the top-down thinking and the bottom-up method. PID control algorithm encoder signal processing and PWM waveform generation etc were realized by the system. The results show that the system structure is simplified and the stability and reliability are improved. A solution of system on a chip is realized to some extent. It has extensive application value in engineering practice. 2011 Trans Tech Publications.
	High precision test method for dynamic imaging of space camera (EI CONFERENCE) 会议论文 OAI收割 2010 IEEE International Conference on Advanced Computer Control, ICACC 2010, March 27, 2010 - March 29, 2010, 445 Hoes Lane - P.O.Box 1331, Piscataway, NJ 08855-1331, United States 作者: Jin L.-X.; Zhang K.; Zhang K.; Zhang K.; Zhang K. 收藏 \| 浏览/下载：35/0 \| 提交时间：2013/03/25 A test method for dynamic imaging of space TDICCD (Time Delay and Integration Charge Coupled Devices) camera was presented in this paper. The test method adopted the PLL (Phase Locked Loop) technology and CMAC (Cerebella Model Articulation Controller) friction compensation as control strategy. Furthermore According to this method a test system for dynamic imaging of space TDICCD camera was designed and implemented. The system simulated the movement of the ground objects relative to the space aerocraft to validate the capability of image speed match and the dynamic imaging quality of TDICCD camera. The design adopted a precision turntable and a drift turntable to simulate the movement around the earth and the drift motion in different latitude due to the rotation of earth of the aerocraft. The turntables were drived by permanent magnet torque motor which was powered by PWM (Pulse Width Modulation). The system adopted DSP (Digital Signal Processor) as the control core and reached a very high performance. The experimental results showed that the steady speed error was better than 0.01 % and the instantaneous speed error reached 0.0267%. The precision of the test system designed met the requirement for dynamic imaging of TDICCD camera. 2010 IEEE.
	Slip motor speed control system based on LPC2136 and low cost CMOS camera (EI CONFERENCE) 会议论文 OAI收割 2010 IEEE International Conference on Advanced Computer Control, ICACC 2010, March 27, 2010 - March 29, 2010, 445 Hoes Lane - P.O.Box 1331, Piscataway, NJ 08855-1331, United States 作者: Yang S.-W. 收藏 \| 浏览/下载：23/0 \| 提交时间：2013/03/25 In this paper Slip motor speed is in the precision of 1 percent in scope of 0 to 1400rpm. Practical application shows that the system is reliable designed the slip motor speed control system for packing rubber strip which is used in plastic steel door and window. The system stable and higher precision of control. The system design provides reference for similar control system and builds the basis for the design of intelligent control system. 2010 IEEE. 32-bit embedded microprocessor LPC2136 as the control core PWM speed control velocity feedback from tachogenerator rubber strip position feedback from the CMOS camera has proved that CMOS camera's image quality meets the engineering requirement
