【Abstract】 The robust control for T-S fuzzy descriptor systems with time-delay is discussed.Departing from traditional approaches,which find a common positive definite matrix for all rules,sufficient conditions to guarantee the robust stability for such fuzzy systems,are derived by using matrix measures of system matrices in the consequent parts of fuzzy rules.These conditions are further transformed into linear matrix inequalities.By solving linear matrix inequalities,a state feedback controller and static output feedback controller that stabilize the considered uncertain time-delay system are obtained.Finally,numerical examples are provided to illustrate the effectiveness of the proposed design method.更多还原
