High performance fuzzy-proportional integral-sliding mode controller for chattering-free speed control of induction motors

This paper proposes a PI controller to be functioned in the steady state area to result in high steady state performance and a sliding mode controller that functions in the transient area to result in high transient performance. To combine these two controllers, an outer fuzzy logic controller is to be implemented to switch between them. This is a solution to the chattering problem of the sliding mode controller for induction motors.
