Abstract: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 faulttolerant 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.
