Fuzzy H∞ output feedback control of nonlinear systems under sampled measurements

Abstract

This paper studies the problem of designing an H∞ fuzzy feedback control for a class of nonlinear systems. A nonlinear systems is first described by a continuous-time fuzzy system model under sampled output measurements. The premise variables of the fuzzy system model are allowed to be unavailable. We develop a technique for designing an H∞ fuzzy feedback control which globally stabilises this class of fuzzy system models. A design algorithm for constructing the H∞ fuzzy feedback controller is given. A numerical simulation example is given to show the potential of the proposed techniques.
