Fuzzy-Model-Based Stabilization of Nonlinear Networked Control Systems
This paper is concerned with fuzzy-model based stabilization of nonlinear networked control systems(NCSs)with time-varying transmission delays and transmission intervals based on a random-delay approach.The real-time distribution of input delays resulting from transmission delays and intervals is modeled as a dependent and nonidentically distributed process.Then a randomly switched Takagi-Sugeno fuzzy system with multiple input-delay subsystems is proposed to model the nonlinear NCSs.Based on an improved Lyapunov-Krasovskii method,which takes into account the real-time distribution of input delays in estimating cross-product integral terms,new sufficient conditions are derive-ed for the exponential stability of the overall systems.The resulting controller design method is equivalent to a nonlinear convex optimization problem with LMI constraints.Numerical examples are presented to substantiate the effectiveness of our results.
