This paper deals with a new design of discrete-time sliding mode control of an induction motor. Indeed, an integral switching surface is developed to ensure a high quality control with a short settling time and small zero steady state error. Besides, the integral tracking errors action improves the nonlinear system robustness and chattering reduction. Real-time experiments results are carried out using a dSpace system with DS1104 control board based on digital signal processor TMS320F240. To highlight the efficiency and applicability of the presented control scheme, a comparative study with other methods is given.
