【Abstract】 The Tagaki-Sugeno (T-S) fuzzy model system is adopted for modeling the uncertain nonlinear discrete system.The guaranteed cost control problem via memoryless feedback controllers is studied for a class of uncertain discrete fuzzy systems with norm-bounded time-varying parametric uncertainty. A sufficient condition for quadratic stability of fuzzy closed loop system is given in terms of linear matrix inequalities (LMIs). The results of the case show that the method is efficient.更多还原
