A new design method of fuzzy sliding mode controller with faster convergence

A sliding mode controller based on adaptive fuzzy logic system for non-linear system with model uncertainty is considered. The adaptive fuzzy logic system here is used to design the change of system structure of sliding mode control and can excellently eliminate the chattering problem in sliding-mode control. By considering the distance of system status and its change to the sliding line, the controller we designed has faster convergence than the fuzzy sliding mode controller designed before. The stability of the controller is guaranteed by the stability theorem of Lyapunov. Finally, simulation results are presented to show the effectiveness of this kind of controller.
