This paper addresses the problem of quadratic stability for a class of uncertain nonlinear systems using fuzzy technique.Fuzzy T-S model and fuzzy logic systems are used to model the nonlinear systems. The fuzzy controller is designed such that the closed-loop system is quadratically stable and satisfies the desired L_2norm bound.The main advantage is that the designer makes no constraint assumption for the approximating error arisen from fuzzy T-S model and the uncertainties in nonlinear systems.Simulation results demonstrate the effectiveness of the developed control scheme.
