Sliding mode control for network control systems with packets dropout

Abstract

In this paper, we investigate the problems of stabilization of networked control systems with packets dropout via delta operator approach. A sliding mode controller is constructed to analyze the stochastic stability of the closed-loop networked control systems. The process of packets dropout is modeled as a Bernoulli process. Sufficient LMI conditions are developed to guarantee the existence of the discrete linear sliding surfaces. By solving the conditions, a linear sliding surface is characterized and a sliding mode controller is designed. Simulation results are given to demonstrate the effectiveness of the proposed approach.
