	Control strategies and error compensation methods of high precision gyro stabilized platform (EI CONFERENCE) 会议论文 OAI收割 30th Chinese Control Conference, CCC 2011, July 22, 2011 - July 24, 2011, Yantai, China Deng K.; Cong S.; Shen H. 收藏 \| 浏览/下载：30/0 \| 提交时间：2013/03/25 Based on the principle of gyroscope and the structure of gyro stabilized platform this paper gives the analysis and comparison of control strategies for stable platform included classical PID control and three kinds of advanced strategies: Fuzzy Control Sliding Mode Variable Structure Control and Active Disturbance Rejection Control. The compensation methods for stable platform's error are also discussed and evaluated based on the sources of error especially for the non-linear friction and gyro drift. The paper provides the reliable methods for recognizing and improving the accuracy of gyro stabilized platform from the control strategies and error compensations. 2011 Chinese Assoc of Automation.
