Vector Control for an Interior Permanent Magnet Synchronous Machine with Maximum Torque per Ampere Strategy

The main objective of this paper is to show a methodology to implement a Maximum Torque per Ampere Strategy (MTPA) in an Interior Permanent Magnet Synchronous Machine (IPMSM). IPMSMs have been broadly used on industry in the last years for having excellent dynamic performance and high power density. In this article, vector control and MTPA theory and criteria are firstly detailed. Then, the mathematical analysis and simulation aspects are presented. Lastly, the speed and torque control responses are exposed. The results show successful responses of the system on steady-state and during transients.
