Abstract

Abstract: This paper studies the H ∞ fuzzy control for a class of coupled differential-difference nonlinear systems with input saturation, bounded disturbance and time-varying delays. The purpose is to design a state-feedback fuzzy controller such that the resulting closed-loop system is locally stable and satisfies a regional H ∞ performance. Delay-dependent sufficient conditions ensuring the existence of the desired controllers are obtained based on the fuzzy-weighting dependent Lyapunov-Krasovskii functional approach and the linear matrix inequality (LMI) technique. Finally, a numerical example is used to illustrate the effectiveness of the proposed design method.
