不确定连续系统基于区域极点配置的鲁棒容错控制

Robust fault-tolerant control for uncertain continuous systems based on regional pole assignment

利用代数Riccati方程和矩阵范数理论,研究了连续系统基于区域极点配置的容错控制问题。给出了系统闭路环极点配置在圆形区域内对执行器失效且具有完整性的一个充分条件;进而讨论了不确定连续系统的闭环极点配置在圆形区域内的鲁棒容错控制问题,且给出了此条件下鲁棒容错控制系统的设计方法。此设计方法是有效的。

By using algebraic Riccati equation and the matrix norm theory, the problem of fault- tolerant control for continuous systems based on regional pole assignment is studied. A sufficient condition that the poles of the closed - loop system are placed in a specific circular region and the system possessing integrity a- gainst actuator failure is presented. Then, robust fault - tolerant control problem for uncerain continuous systems based on regional ple assignment is discussed. The design method of robust fault - tolerant control of uncertain continuous systems based on regional pole assignment is gived. The desgned metod is effective.
