Reliable Control of Networked Switched Systems Subject to Random Sensor and Actuator Faults

In this paper, the problem of robust H-infinity control is considered for a class of networked switched systems (NCS) with state unavailable. The faults are assumed to occur from the sensor to the controller and from the controller to the actuator, simultaneously. The missing probability for each channel of the sensor-to-controller and controller-to-actuator is different and is governed by a random variable that satisfying certain probabilistic distribution in the interval [0,theta] (theta >= 1). First, an observerbased feedback controller is designed. And then, by adopting the average dwell time method, a sufficient condition for the mean-square exponential stability and a guaranteed H-infinity performance of the system is obtained. Finally, a numerical simulation example is given to demonstrate the effectiveness of the proposed method.
