Adaptive fuzzy sliding mode control scheme for a class of uncertain nonlinear systems

Abstract

Abstract: The tracking problem for a class of unknown nonlinearities systems with unknown disturbance is considered. By utilizing Lyapunov stability theory, the adaptive fuzzy sliding mode controller is established. And the upper knowledge of the model uncertainties and the model of the nonlinear systems are not required to be known. The effectiveness of the proposed fuzzy adaptive controller is illustrated throughout the simulation results.

Key words: unknown nonlinear systems, adaptive fuzzy control, sliding mode control
