摘　　要：研究了一类具有参数不确定性的非线性网络化控制系统,同时考虑数据丢包和网络时延的影响,利用T-S模糊模型对其进行描述。针对既有传感器失效,又有执行器失效的故障情形,引入一种状态反馈控制器,并基于Lyapunov稳定定理以及引入的积分不等式,给出了在传感器失效和执行器失效故障下具有鲁棒完整性的充分条件,并进行了证明。最后通过算例仿真证明了这种设计方法的有效性和可行性。A class of nonlinear networked control systems with parameter uncertainty is studied in this paper.Considering the effect of network delay and data packet loss,the t-s fuzzy model is used to describe the system,and a state feedback controller is introduced to deal with the problems of sensor failure and actuator failure.Based on the Lyapunov stability theorem and the integral inequality introduced,the sufficient conditions of robust integrity under the conditions of actuator failure and sensor failure are proposed and verified.Finally,the effectiveness and feasibility of this design method are proved by numerical simulation.
