Passivity analysis for fuzzy time-delay systems based on fuzzy Lyapunov-Krasovskii functionals

This paper is concerned with the problem of passivity analysis for continuous-time Takagi-Sugeno (T-S) fuzzy systems with time-varying delays. By using different kinds of fuzzy Lyapunov-Krasovskii functionals, both delay-independent and delay-dependent conditions for the considered fuzzy system to be passive are presented in terms of linear matrix inequalities (LMIs). Numerical examples are provided to demonstrate the effectiveness of the proposed passivity results.
