The delayed feedback control problem is studied for a class of continuoustime fuzzy systems with timevarying delay. Based on a new fuzzy LyapunovKrasovskii functional (LKF)
a delay-dependent stability criterion is derived for the open-loop fuzzy systems. Less conservative results are obtained by considering the additional useful terms when estimating the upper bound of the derivative of LKF and introducing new fuzzy free weighting matrices. Then based on parallel distributed compensation (PDC)
a delay-dependent stabilization condition is derived in terms of linear matrix inequalities (LMIs) and the corresponding controller can be obtained by solving a set of LMIs. Finally
simulation examples show the effectiveness of the proposed method.
