Passive control for fuzzy system with time-delay

In this paper, a delay partitioning approach is introduced to solve problems of passivity and passification for continuous T-S fuzzy system with time delay. By constructing a Lyapunov-Krasovskii functional, delay-dependent passivity/passification performance conditions are formulated in terms of linear matrix inequalities(LMIs). Finally, a numerical example is used to illustrate the effectiveness of the proposed approaches which can futher reduce conservatism.
