| 摘 要： | 研究一类不确定非线性切换系统的鲁棒容错控制问题,当执行器失效或部分失效时,利用Lyapunov函数法建立切换闭环系统混杂状态反馈容错控制器存在的充分条件;然后运用线性矩阵不等式将鲁棒容错控制器设计问题转化为一组线性矩阵不等式的可行解问题,从而借助Matlab中线性矩阵不等式工具箱求解;最后通过数值算倒验证了所提出设计方法的有效性.

| Abstract: | The robust fault-tolerant control is studied for a class of uncertain switched systems.When actuator failures or partial failures,a sufficient condition for the existence of hybrid state feedback fault-tolerant controllers for closed-loop switched systems is obtained based on Lyapunov function method.Then by linear matrix inequlities(LMI)approach,the design of robust fault-tolerant controllers is transformed into the feasible problem of some certain LMI system.The controllers can be efficiently solved by me... |
