Abstract: In this research work the performance of closed loop speed control of Indirect Field Oriented controlled Induction motor using Sliding Mode Controller is described. The phenomenon of chattering of the control signal, which is the major disadvantage of Sliding Mode Control is overcome by applying Exponential Reaching Law. In the proposed method an exponential function is used as the sliding variable which dynamically adapts with the variations of the controlled system. The mathematical modeling of complete system is done and the simulated results are compared with conventional sliding mode controller and classical PID controller. The simulation results verify the superior performance and chattering reduction by employing Sliding Mode Controller with Exponential Reaching Law..
