Fuzzy Control of Uncertain Nonlinear Networked Control Systems with Random Time-delays

Abstract

This paper investigates the stabilization problem for a class of nonlinear uncertain networked control systems (NCSs) with random communication time-delays. The nonlinear NCSs are described by a set of local linear systems which are combined using a Takagi-Sugeno model. Both sensor-to- controller and controller-to-actuator random network-induced delays are considered. Markov processes are using to model these random network-induced delays. Based on the Lyapunov-Razumikhin method a mode-dependent state feedback controller is proposed to stabilize this class of systems. Sufficient conditions for the existence of a mode-dependent state feedback controller for this class of NCSs are derived. The effectiveness of the proposed design methodology is verified by a numerical example.
