Abstract

This paper considers decentralized H_infin fuzzy filter design for fuzzy large-scale systems. The T-S fuzzy large-scale system consists of N T-S fuzzy subsystems. The decentralized H_infin filter is designed such that the asymptotic stability and a prescribed H_infin performance index is guaranteed for the overall filtering error system. A sufficient condition for the existence of such a filter is established by using linear matrix inequalities (LMIs) that are numerically feasible. Simulation example is given to show the effectiveness of the present approach.
