Abstract :
A delay-dependent robust control problem for a class of uncertain T-S fuzzy system with delay is presented. Based on a Lyapunov-Krasovskii functional and free-weighting matrices with time-delay, a new delay-dependent robust stability criterion is proposed and proved for the close-loop fuzzy system. Finally , simulation results are presented to show the effectiveness of the approach.
