摘要
针对一类具有参数不确定性的非线性网络化控制系统,同时考虑网络延时和数据包丢失的影响,利用T-S模型对其进行描述,通过构造Lyapunov-Krasovskii泛函,以线性矩阵不等式形式给出并证明确保非线性网络化控制系统(NCS)在执行器失效故障时,具有鲁棒容错性依赖的充分条件。仿真算例说明了容错算法的可行性和有效性。
As for a class of nonlinear networked control system with parameter uncertainties, considering both network-induced delay and packet dropout in transmission, based on a T-S fuzzy model, and by using Lyapunov-Krasovskii functional, the delay-dependent sufficient condition of robust integrity for NCS with failures of actuator and sensor is analyzed in this paper. And the robust fault-tolerant controller gain can be obtained by solving several linear matrix inequalities. Finally, a simulation example illustrates the effectiveness and the feasibility of the proposed approach.
