In this paper, the delay-dependent non-fragile robust H∞ control for a class of fuzzy descriptor time-delay systems with norm-bounded parameter uncertainties is investigated. First, a new delay-dependent non-fragile H∞ stabilization method is proposed via a state feedback fuzzy controller, which guarantees the closed-loop nominal system to be regular, impulse free, asymptotically stable. Then, sufficient...
In this paper, the delay-dependent non-fragile H∞ control for a class of fuzzy descriptor time-delay systems is investigated. A non-fragile controller via state feedback is proposed, which guarantees the closed-loop system to be regular, impulse free, asymptotically stable and satisfies the H∞-norm constrain. The sufficient conditions for the solvability of this controller design problem are presented...
This paper concerns on the problem of delay-dependent guaranteed cost control for a class of nonlinear descriptor delay systems which can be represented by the Takagi-Sugeno (T-S) fuzzy descriptor models with time-varying delays. A quadratic cost function is used as a guaranteed performance index. Based on the delay-dependent Lyapunov-Krasovskii functional approach, sufficient conditions for the existence...
This paper focuses on the problem of robust guaranteed cost control for a class of nonlinear systems described by the Takagi-Sugeno (T-S ) fuzzy descriptor model with time-varying delay and parameter uncertainties. The less conservative sufficient conditions for the existence of robust guaranteed cost controller via state feedback are given in terms of linear matrix inequalities (LMIs). And the design...
This paper investigates the problems of robust quadratic stability and robust Hinfin control for a class of fuzzy descriptor systems with time-varying delay and parameter uncertainties. A new Takagi-Sugeno fuzzy descriptor system model with disturbance is proposed. The regularity, impulse free and quadratic stability for the system are defined. A state feedback Hinfin controller is determined, which...
