Controller Design for Nonlinear Networked Control Systems with Time-varying Delay Based on T-S Fuzzy Model

Abstract

To controller design and stability analysis for nonlinear Networked Control Systems (NCSs) with time-varying delay, based on the Takagi–Sugeno (T-S) fuzzy model, a controller design scheme was proposed to achieve desired control performance for nonlinear NCSs via state feedback. According to the Lyapunov method, the sufficient condition for the existence of the control law was presented. Simulation results show the proposed methods are effective to make the closed-loop system asymptotically stable for all admissible time delay and can further guarantee the expected performance index for nonlinear NCSs with time-varying delay
