Robust Adaptive Sliding Mode Control for Switched Networked Control Systems With Disturbance and Faults

Abstract

In this paper, the problem of switched networked control systems (SNCSs) with external disturbance and actuator /sensor faults is investigated. Meanwhile, the communication constraints such as network-induced delay, packet dropouts, and packet disorder are considered in a communication network. A robust adaptive sliding mode control method is proposed for disturbance damping and faults tolerance, which is designed on an observer and second-order discrete-time adaptive sliding mode function. Furthermore, the reachability of sliding motion is proved. Then, the networked predictive control method is employed to compensate the communication constraints. Finally, the stability of the closed-loop system is proved, and a numerical example and a mechanical system simulation example are executed to verify the effectiveness of the proposed method.
