Abstract :
In this paper, we investigate the problems of local stability analysis and synthesis for T-S fuzzy systems with time-delay. Firstly, the notion of local stability for T-S fuzzy systems with time-delay is introduced. Then, by using non-quadratic Lyapunov functions and LMI technique, a sufficient condition for the open-loop system to be locally stable is derived, by which a nonlinear controller is designed. At last, an example is presented to illustrate our results
