By adopting finite element analysis technique  the structure of the space telescope was analyzed. The analysis results indicate that the surface profile accuracy of the mirrors reach to RMS 8.0nm with the working circumstances 4C uniform temperature change and space micro-gravity  the base frequency of the structure was 115 Hz. It shows that the designed structure has sufficiently high dynamic and static stiffness and thermal dimensional stabiLity. This space optical telescope is very suitable for little satellite application. 2011 IEEE.   Research on computer control strategy for optical electric tracking system (EI CONFERENCE) 会议论文  OAI收割 2011 IEEE International Conference on Mechatronics and Automation, ICMA 2011, August 7, 2011 - August 10, 2011, Beijing, China 作者:  Li M. 收藏  |  浏览/下载：23/0  |  提交时间：2013/03/25 In this paper  mathematic model and computer control strategy for optical electrical tracking system have been researched and discussed. First  the system's structure and its work process have been analyzed. Second  according to the system's moving law  the system's mathematic model has been built. As to the computer control strategy  trigger guiding  two closed loop PID control method as well as compound control method have been applied to satisfy the tracking accuracy. Third  we apply the bilinear transformation to get the digital system  and the sample time is 800Hz. The simulation results indicate that the maximum tracking error can be limited to less than 0.5 and the regulator time can be 0.04s. Then the control project resonance frequency should be more than 200Hz and the sample frequency should be more than 400Hz to meet the control accuracy requirement. So we can conclude that the system indexes such as swiftness  high accuracy as long as real time have been satisfied. And the requirement of mechanical property has been present which is very useful to mechanical working. 2011 IEEE.   Research on servo controller for high speed tracking system (EI CONFERENCE) 会议论文  OAI收割 2011 International Conference on Mechatronic Systems and Automation Systems, MSAS 2011, July 23, 2011 - July 24, 2011, Xi'an, China 作者:  Li M. 收藏  |  浏览/下载：17/0  |  提交时间：2013/03/25 To meet requirement of swiftness and minimization for the tracking system as well as realize horizontal high accuracy tracking measurement  the automatic servo tracking measurement system has been designed. The two closed loop control  bisection method and compound control have been applied into the system. Experimental results show that the maximum tracking error can be limited to less than 0.5and the regulator time can be 0.04s. The control project resonance frequency should be more than 200Hz and the sample frequency should be more than 400Hz to meet the control accuracy requirement. And these specific mechanical properties indexes are useful to mechanical working to make sure the design can be realization. So the research in this paper has important value to the engineering practice.

When optical tracking system working  test equipment can not be fixed. Therefore  from the electromagnetic radiation theory  the paper analyzed the electromagnetic radiation of the power drive module. From it  determine the EMC pre-compliance test method for electromagnetic radiation of power drive module. Based on Test results  calculate the interference voltage of wire in Conductive ring  and then determine the corresponding EMC method. The results show that  when The power drive module Radiate Electromagnetic waves  wires would coupled common mode interference voltage  its frequency is 3MHz  amplitude is about 10V  it would interfered the operation of sensor. By reducing the area of ground loops  used shielded cables  final rule out the interference. 2010 IEEE.
