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.   Generation of Preformed Plasma Channel for GeV-Scaled Electron Accelerator by Ablative Capillary Discharges 期刊论文  OAI收割 plasma science and technology, 2011, 期号: 13 DENG Aihua (邓爱华), LIU Mingwei (刘明伟), LIU Jiansheng(刘建胜),; LU Xiaoming (陆效明), XIA Changquan (夏长权), XU Jiancai (徐建彩); WANG Cheng (王成), SHEN Baifei (沈百飞), LI Ruxin (李儒新); XU Zhizhan (徐至展), K.
