Abstract :
In this paper, a fuzzy, adaptive tracking control scheme for a class of unknown dynamical nonlinear systems is presented. Since both parametric uncertainties and unmodeled dynamics are present in the nonlinear system, we design different controllers, respectively. Based on Lyapunov theory, we discussed the stability of the closed loop system and the convergence of the tracking errors
