Decoupled Sliding Mode Control for an Induction Motor

This paper represents a decoupled control strategy using sliding surface based on sliding mode controller for speed control of induction motor . The decoupled method provides a simple way to achieve asymptotic stability for induction motor . A strategy of sliding mode control is used, the decoupling method in this study uses two sliding mode controller for flux and speed . Then it compared by using PI controller which control flux and speed of the motor. Both controllers are simulated using SIMULINK . Simulation results are presented the effectiveness and good performance of the decoupling sliding mode control by considering the effects of the variations of the load torque.
