Abstract
Time-delays,due to the information transmission between subsystems,naturally exist in large-scale systems and the existence of the delay is frequendy a source of instability.This paper considers the problems of robust non-fragile fuzzy control for a class of uncertain discrete nonlinear large-scale systems with time-delay and controller gain perturbations described by T-S fuzzy model.An equivalent T-S fuzzy model is represented for discrete-delay nonlinear large-scale systems.A sufficient condition for the existence of such non-fragile controllers is further derived via the Lyapunov function and the linear matrix inequality(LMI)approach.Simulation results demonstrate the feasibility and the effectiveness of the proposed design and the proper stabilization of the system in spite of controller gain variations and uncertainties.关键词
