    Abstract
  • Based on analyzing disadvantages of the existing adaptive fuzzy control approach, a new design method of adaptive fuzzy controller(AFC) for a class of nonlinear systems is proposed. In order to ensure the consistency of the closed-loop system performances, before the AFC is applied, a supervisory controller is used to drive initial tracking errors to a preset closed area, and then the AFC can drive the tracking errors of the closed-loop system to pre-specified neighborhood in the presence of unknown approximation errors of the fuzzy logic system. Finally, simulation results verify the validity of this method.
