摘　　要：研究一类具有参数不确定的网络化控制系统,同时考虑数据丢包和网络时延对系统性能产生的影响,将服从伯努利丢包的网络控制系统视为以一定速率切换的开关。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理论和异步动态系统理论,对网络控制系统进行鲁棒容错控制问题的研究,给出系统在此情形下保持渐近稳定的充分条件,通过求解线性矩阵不等式,得到了执行器和传感器同时失效情况下的容错控制器。最后通过算例仿真证明了所提方法的有效性。A class of networked control systems with uncertain parameters was studied. Considering the influence of data packet loss and network delay on system performance, the networked control systems subject to Bernoulli packet loss were considered as switching switches at a certain rate. As well as against both sensor failure and actuator failure fault situation, a state feedback controller was introduced, and based on Lyapunov theory and asynchronous dynamical system theory, the network control system based on robust fault-tolerant control problem was studied, the sufficient conditions for keeping asymptotic stability in this case was given.By solving the linear matrix inequality, the fault-tolerant controller in case of simultaneous failure of actuator and sensor was designed. Finally, an example was given to demonstrate the effectiveness of the proposed method.
