针对一类执行器故障连续系统的保性能控制设计

Guaranteed Cost Control for Uncertain linear Systems under Actuator Failures

本文利用线性矩阵不等式 (LMI)方法 ,讨论了一类存在执行器故障不确定连续系统的保性能控制问题 ,给出了故障时系统保性能状态反馈控制器存在的充分条件并应用基于LMI的凸优化方法实现了针对系统故障的最优保性能状态反馈控制器设计。仿真实例验证了该方法的有效性。

The problem of guaranteed cost control for a class of linear uncertain systems with actuator failures is concerned. Based on LMI, sufficient condition for the existence of guaranteed cost state feedback controller is given and the design of optimal guaranteed cost state feedback controller is presented in terms of the convex optimization approach. A simulation example demonstrates the effectiveness of the design method.
