Robust Fault-tolerant Guaranteed Cost Control for A Class of Uncertain Networked Control Systems with Time-delay

针对一类具有时滞且模型中具有参数摄动的网络控制系统,研究在执行器发生故障的情况下系统具有鲁棒保成本可靠控制器设计问题。根据Lyapunov稳定性理论和容错控制理论得到满足系统存在鲁棒保成本控制器的一个矩阵不等式,进而将这个矩阵不等式转化为线性矩阵不等式,从而得出系统渐近稳定的充分条件和系统的保成本上界。最后用实例仿真证明结论的有效性。

This paper focuses on a class of networked control system with time-delay and the uncertainty parameters, consider actuator fault, to study the design of robust guaranteed cost reliable controller. Based on the Lyapunov stability theo- ry, fault-tolerant control,under the case Of existence robust guaranteed cost controller get a matrix inequality,then the ma- trix inequality turn into liner matrix inequality（LMI） . As a result,the system of sufficient condition of robust fault-tolerant guaranteed cost control and upper bound of guaranteed cost system is given. Finally, an application simulation results prove the effectiveness of the conclusion.
