高空大气压力模拟系统自适应鲁棒控制
Adaptive robust control for high altitude atmosphere simulator system
摘要
Abstract
A simple and practical leakage model of the servo device w as presented ,and an adaptive ro‐bust controller was designed for high altitude atmosphere simulator ,which was sensitive to the leak‐age of the servo device and asymmetry between the charging and discharging process .The precision could be improved with the online update of the leakage coefficient ,and the leakage coefficient could be limited in a certain range with the projection mapping .At last ,the system stability was proved by Lyapunov principle .Experiment results show that the proposed controller is effective in dealing with the asymmetry of the system ,and the precision and response speed can be improved .关键词
