Implementation of a Model Predictive Control for IPMSM Using MTPA and Flux-Weakening Strategies in EV Traction Drive

This paper introduces a Model Predictive Control (MPC) approach incorporating Maximum Torque per Ampere (MTPA) and Flux Weakening (FW) techniques tailored for an Internal Permanent Magnet Synchronous Motor (IPMSM), targeting its application in Electric Vehicles (EVs). The MPC strategy controls the stator currents while taking into account the voltage synthesis capability of the inverter. On the other hand, the MTPA strategy ensures high operational efficiency by selecting the smallest current reference vectors for the desired torque and, the FW strategy allows operation at higher speeds, increasing the operating range. Finally, the simulation results are presented to demonstrate that the proposed method is effective for different load conditions.
