Assessment of Direct Torque Control strategies for induction machine

Direct Torque Control (DTC) has becoming the industrial standard for Induction Machine (IM) torque control by means of very simple control schemes. This paper presents a contribution for detailed comparison of Direct Torque Control strategies (Classical DTC, SVM-DTC and Fuzzy DTC) for Induction Machine. The performances of those various methodologies are evaluated and compared by simulation in terms of torque and current ripples, and transient response.
