Abstract

A direct adaptive tracking control architecture based on fuzzy logic is developed for a class of nonlinear dynamic systems. In the procedure, the controller is composed of fuzzy approximate controller and fuzzy sliding mode compensating controller. Global asymptotic stability of the algorithm is established in the Lyapunov sense, with tracking errors convergence to a neighborhood of zero. Simulation results demonstrate the effectiveness of the proposed algorithm
