Delay-Dependent H∞ Filter Design for Fuzzy Descriptor Continuous-Time Systems

This paper discusses the H infinity filtering problem for T-S fuzzy descriptor systems with time-delay. An Interval delay-dependent sufficient condition for the existence of a H infinity filter is given in terms of linear matrix inequality (LMI) by using of the Lyapunov-Krasovskii theorem and the free-weighting matrix technique, which guarantees the filtering error system to be regular, impulse-free and stable with a prescribed H infinity performance index. A numerical example is given to illustrate the effectiveness of the method.
