Abstract :
An adaptive fuzzy control system for a class of uncertain nonlinear systems is presented in this paper. Fuzzy basis function expansions are used to approximate the unknown dynamics in a nonlinear system. The parameters of the FBF expansions are updated using an adaptive law resulted from the Lyapunov-based design. Semi-global asymptotical tracking to a reference trajectory upto a ultimately bounded error is achieved with the proposed control. The effectiveness of this method is demonstrated through simulations.
