Stability Analysis for Time-Delay Fuzzy Systems Using Augmented Lyapunov Functional Approach

This paper is concerned with the asymptotic stability of Takagi-Sugeno (T-S) fuzzy systems with state-delay. The state-of-the-art of delay-dependent stability analysis method is provided in terms of linear matrix inequalities (LMIs). The augmented Lyapunov functional method is used to establish delay-dependent criteria. Theoretical comparisons are done among the present and existing results. Illustrative example is given to convince the less conservativeness of our method
