Abstract

Multiphase ac machine drives are now considered for various applications as they afford numerous benefits over their three-phase counterparts. As a result, using five-phase machines in electric drive systems is becoming more common in many industries. This paper presents a five-phase Synchronous Reluctance Motor (SynRM) design with a Direct Torque Control (DTC) strategy to establish the motor's dynamic simulation and reduce torque ripple resulting from the anisotropic structure of rotor to be ±5 and to control the motor speed at acceleration and deceleration. A five-phase voltage source inverter pulses are generated using a specific DTC Space Vector Modulation (DTC-SVM) technique. There are two look-up tables derived from stator flux linkage and electromagnetic torque control by using proper voltage space vectors. The technique used in this paper is considered a fast and straightforward method comparable to the other techniques. This paper also includes a control block schematic and a description of manners performance under various load situations and varied reference speeds at the transient and steady-state conditions. Lastly, simulation results achieved via Matlab/Simulink software show that it was a perfect control system because the motor's real speed value strictly follows the reference speed, and all results are conventional and regular.
