Abstract

Though sliding mode variable structure controller has good robustness and high stability, its chattering phenomenon is widely exist. A fuzzy sliding mode controller is designed based on exponential approach law by combining sliding control and fuzzy control in this paper. The computer simulation is applied to verify the advance of the fuzzy sliding mode controller and the controller is applied to ship course control. The simulation results verify this controller is very effective.
