Direct Torque Control for Double Star Induction Motor

Abstract

This paper describes a direct torque control (DTC) of dual star induction motor (DSIM). This machine possesses several advantages over conventional three-phase machine and is also known as the six-phase induction machine. The research has been underway for the last two decades to investigate the various issues related to the use of six-phase machine as a potential alternative to the conventional three-phase machine. Though six-phase machines have existed for some time, in the literature very few papers discuss DTC for six-phase motors. Therefore, in this work an investigation is reserved to the application of this type of control to the DSIM. The DTC uses the instantaneous values of voltage vector where each reference voltage vector is computed with a simple DTC algorithm. Finally, simulations results obtained from MatLab/Simulink are presented followed by a discussion.
