【摘要】 研究了一类不确定网络化控制系统的容错保性能控制问题。基于Lyapunov稳定性理论和LMI方法,采用有记忆状态反馈控制策略,针对含有参数不确定性的网络化控制系统在执行器发生失效故障时推证出了一个保证闭环网络化控制系统满足一定控制性能指标的充分条件,进而通过将矩阵不等式转化为线性矩阵不等式,给出了容错保性能控制器的求取方法。最后以仿真算例验证了此种方法的可行性和有效性。更多还原

【Abstract】 The problem of guaranteed cost fault-tolerant control for networked control systems(NCSs) is discussed in this paper.Based on Lyapunov stability theory and Linear Matrix Inequality(LMI) ,the sufficient conditions which can meet a cost function for closed-loop networked control systems possessing robust integrity against actuator failures are given by adopting memory state feedback control law,and the robust fault-tolerant controller is designed via solving several linear matrix inequalities.Finally,the numerical example is given to demonstrate the effectiveness and feasibility of the proposed approach.更多还原
