摘要: 针对一类参数不确定的网络控制系统,在节点部分失效下的情况下,研究了鲁棒H容错控制。通过构造适当的Lyapunov函数,并运用鲁棒H控制理论和线性矩阵不等式方法(LMI),导出了网络控制系统鲁棒H控制器存在的条件及具体方法。通过一个仿真算例证明了该方法的可行性和有效性。

Abstract: The problem of robust H fault-tolerant control is investigated for a class unceitain Networked Control Syetem(NCS) with nodes partial failure. Based on Linear Matrix Inequality(LMI) techniques, and constructing a suitable Lyapunov Lyapunov-Krasovakii function, a suffcient conditon for NCS with robust Hfault-tolerant controller and the design approach of the controller are obtained. A simulation example is used to illustrate the effectiveness and the feasibility of the proposed approach.
