This paper has attempted to improve the speed control performance of an indirect field oriented (IFO) induction motor drive system by using a continuous sliding mode controller. The proposed continuous sliding mode controller is robust to load changes and system disturbances which are unique features of discontinuous sliding mode control. Also it is free from chattering which is the main problem of discontinuous sliding mode control. The proposed controller can also overcome the performance degradation and avoid tedious tuning process associated with the PI controller. The results of PI and sliding mode controller (SMC) are compared through extensive simulation and experimental work. These results prove that the proposed controller is robust to load changes and system disturbances and can also follow different command trajectories very well without re-tuning of the controller.
