针对一类具有时延和丢包的非线性网络化控制系统,采用动态输出反馈控制策略,在对时延分段处理的情形下,基于T-S模糊模型,通过构造时滞依赖的Lyapunov-Krasovskii泛函,推证出确保系统在执行器发生失效故障时具有完整性的少保守性充分条件,并以求解线性矩阵不等式的方式给出控制器的设计方法.最后,以仿真算例验证所述方法的可行性和有效性.%For a class of nonlinear networked control system with time-delay, based on T-S fuzzy model and dynamic output feedback strategy, and by using Lyapunov-Krasovskii functional, a less conservative delay-dependent sufficient condition of integrity for NCS with failures of actuator was derived and verified on the model of piecewise time-delay. And the design method of fault-tolerant controller was given by solving several LMIs. Finally, by performing a simulation, the effectiveness and feasibility of the proposed approach were verified.
