DTC Method for Vector Control of 3-Phase Induction Motor under Open-Phase Fault

Abstract

Three-phase Induction Motor (IM) drives are widely used in industrial equipments. One of the essential problems of 3-phase IM drives is their high speed and torque pulsation in the fault conditions. This paper shows Direct Torque Control (DTC) strategy for vector control of a 3-phase IM under opencircuit fault. The objective is to implement a solution for vector control of 3-phase IM drives which can be also used under open-phase fault. MATLAB simulations were carried out and performance analysis is presented.
