| 摘 要： | 基于T-S云模型对一类具有参数不确定的非线性网络化控制系统,考虑网络延时和丢包的影响,通过构造Lyapunov-Krasovskii泛函,推证出确保非线性网络化控制系统在执行器或传感器发生失效故障时具有保性能鲁棒容错性能的时滞依赖充分条件,并以求解线性或非线性矩阵不等式的方式给出控制器的设计方法.最后以一个仿真算例验证文中所述方法的可行性和有效性.

| Abstract: | Aimed at a class of nonlinear networked control system(NCS) with parameter uncertainty,based on the T-S cloud model,and taking the influence of both network-induced time-delay and packet dropout in transmission into consideration,the sufficient condition of time-delay dependence was derived and verified by using Lyapunov-Krasovskii functional approach,so that robust-guaranteed fault-tolerant performance of the nonlinear NCS with failures of actuator and sensor was definitely guaranteed.A design method of the controller could given by solving several linear or nonlinear matrix inequalities.Finally,the effectiveness and the feasibility of the proposed approach was verified by means of an illustration of simulation computation. |
