Finite-Frequency Static Output Feedback H_∞ Control of Continuous-Time T-S Fuzzy Systems

摘要

This paper is concerned with finite-frequency static output feedback (SOF) H-infinity control for a class of continuous-time Takagi-Sugeno (T-S) fuzzy systems. With the aid of the generalized Kalman-Yakubovich-Popov (GKYP) lemma, sufficient conditions for the existence of the finite-frequency SOF H-infinity control are presented. The bilinear matrix inequalities are converted to a set of linear matrix inequalities, with the aid of some special derivations. Two practical examples are given to demonstrate the effectiveness of the proposed method.
