摘要
研究了范数有界参数摄动情况下的不确定线性系统的鲁棒容错控制问题.采用代数的方法给出了在不确定线性系统同时存在执行器失效的情况下,闭环系统具有鲁棒性和完整性的一个充分条件。同时应用线性矩阵不等式方法给出了线性不确定系统对执行器失效具有完整性的设计方法.数值算例表明文中给出的两种算法具有简单有效的特点。
The problem of robust fault-tolerance control for uncertain linear systems is considered in this paper. A sufficient condition is proposed which can guarantee the closed-loop systems possessing robustness against actuator failures. An algebraic approach is used to prove the existence of the desired controllers, and two methods, the analytical expression method and LMI method, to solve the controllers are given. The simplicity and the effectiveness of the two methods are demonstrated with a numerical example.
