Abstract: The Space Vector Modulation based direct torque control is a common solution which is used to solve the conventional DTC’s problems, such as high torque ripple and variable switching frequency. Moreover control performance is improved by replacing PI controller in the speed regulation loop by a higher order sliding mode controller. This controller is based on second order super twisting strategy. Furthermore, IM energy optimization is treated as the second objective of this paper. A proposed model based loss minimization strategy is presented for efficiency optimization. The strategy chooses an optimal flux magnitude for each applied load torque
