Static output feedback control design with guaranteed cost of Takagi-Sugeno fuzzy systems

Abstract

The paper is concerned with control design via static output feedback controller for fuzzy systems. Many results on the state feedback control design have been given in the literature. In the actual situation, however, the state of the system is rarely measured and the output feedback control design is desired. In this paper, guaranteed cost control via output feedback control for fuzzy systems is considered and a control design of stabilizing controllers with guaranteed cost is proposed. The stability analysis of the closed-loop system and controller design are given in terms of LMI conditions, which are less conservative than the existing results.
