Abstract :
In this paper, a robust discrete-time sliding mode speed controller for induction motor drives is proposed. A nonlinear sliding surface is used to achieve fast response with low overshoot. A very simple control law is proposed in order to avoid torque oscillations inherent to usual discrete-time sliding mode design techniques. With the proposed design methodology, discrete-time sliding mode existence conditions are ensured. Simulation and experimental results show the effectiveness of the proposed algorithm
