This research presents an optimal fuzzy sliding mode controller to control a chaotic system. In this method, Bees algorithm has been used to optimize two objectives, an error integral and control input integral. First, a fuzzy sliding mode control for this system has been investigated, then using Bees algorithm to optimize response of chaotic system. The results show that optimal Bees sliding mode fuzzy control method are much effective than conventional sliding mode controller and fuzzy sliding mode controller.
