Abstract

This paper investigates robust and non-fragile H_infin controller design for the affine fuzzy large-scale systems, which are composed of a number of T-S affine fuzzy subsystems with interconnections. According to the Lyapunov direct method and the decentralized control theory of large-scale systems, a sufficient condition in the form of LMIs which guarantees the existence of state feedback H_infin control for affine fuzzy large-scale systems is proposed. A numerical example is given to demonstrate the fuzzy H_infin controller design procedure and its effectiveness.
