Abstract:This paper addresses the stability problem of fuzzy large-scale systems (FLSSs) with uncertainties and arbitrary time-varying delays. The stability conditions, which are less conservative and more applicable than the existing results, are derived by a novel Lyapunov-Krasovskii functional method and expressed in terms of linear matrix inequalities (LMIs). Two examples are given to demonstrate the correctness and advantage of our theoretical results.
Keywords:Lyapunov-Krasovskii functional   Fuzzy large-scale system   Uncertainty   Time-varying delay   Takagi-Sugeno fuzzy model
