【Abstract】 The guaranteed cost control problem via memory less feedback controllers is studied for a class of fuzzy dynamic time-delay systems with norm-bounded time-varying parametric uncertainty. A sufficient condition for the stability of fuzzy closed-loop system is given in terms of linear matrix inequalities (LMIs). All allowable uncertain closed-loop systems are guaranteed to be stable. For a given quadratic cost function, the cost is bounded in a limitation. The simulation results show that the control method is effective.更多还原
