Robust Control of a Class of Uncertain Fuzzy Systems

Abstract

Robust stabilization of a class of uncertain fuzzy systems is considered in this paper. The fuzzy systems not only exit disturbances which do not satisfy the so-called matching condition and contain uncertainties in the input channel, but have uncertainties in the state matrix. By using Lyapunov function, the robust state-feedback controllers are constructed. The controllers guarantee that the states of systems are robust stabilization. A numerical example is given to show the effectiveness of our method.
