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.   Stability of Mechanical Properties for Submicrometer Single-Crystal Silicon Cantilever Under Cyclic Load 期刊论文  OAI收割 journal of microelectromechanical systems, 2011, 卷号: 20, 期号: 1, 页码: 178-183 Zhu YF; Zhang FX; Yang JL; Zheng HY; Yang FH 收藏  |  浏览/下载：58/8  |  提交时间：2011/07/06 Cyclic  mechanical property  resonant frequency  stability  submicrometer-thick cantilever  ENERGY-DISSIPATION  STRUCTURAL FILMS  THIN-FILMS  FATIGUE   GENERALIZED p-VALUES FOR TESTING REGRESSION COEFFICIENTS IN PARTIALLY LINEAR MODELS 期刊论文  OAI收割 JOURNAL OF SYSTEMS SCIENCE & COMPLEXITY, 2010, 卷号: 23, 期号: 6, 页码: 1118-1132 作者:  Hu, Huimin;  Xu, Xingzhong;  Li, Guoying   |  收藏  |  浏览/下载：18/0  |  提交时间：2018/07/30 Fiducial inference  frequency property  generalized p-value  hypothesis testing  partially linear model   Frequency response characteristics of target electric property with long bipole large power control source 期刊论文  OAI收割 CHINESE JOURNAL OF GEOPHYSICS-CHINESE EDITION, 2009, 卷号: 52, 期号: 1, 页码: 275-280 作者:  Di Qing-Yun;  Wang Guang-Jie;  Wang Miao-Yue;  Wang Ruo   |  收藏  |  浏览/下载：17/0  |  提交时间：2018/09/26 Long bipole  Large power  Far distance  Rock property  Resistivity-frequency response
