Abstract

This research study investigates the design of field-oriented control (FOC) for permanent magnet synchronous machines (PMSM), used for railway applications. The study aims to examine the speed and the torque control methods as well as the torque contribution of the saliency by implementing the field weakening (FW) and the maximum torque per amp (MTPA) techniques. The FW strategy provides a wider speed spectrum for the motors, and on the other hand, the MTPA enables higher output torque with better efficiency, as illustrated in the preliminary findings. Therefore, these strategies appear suitable for controlling the PMSM in electrified transport applications as validated in this study through the MATLAB/Simulink platform.
