Maximum Efficiency per Torque Control of Permanent-Magnet Synchronous Machines

Abstract: High-efficiency permanent-magnet synchronous machine (PMSM) drive systems need not only optimally designed motors but also efficiency-oriented control strategies. However, the existing control strategies only focus on partial loss optimization. This paper proposes a novel analytic loss model of PMSM in either sine-wave pulse-width modulation (SPWM) or space vector pulse width modulati...

Traction Permanent Magnet Synchronous Motor Torque Control with Flux Weakening

The paper deals with analysis of dynamic behavior of a feedback flux weakening control of PMSM traction drive for light vehicles. The PMSM flux weakening is very important for traction drives. Two torque control structures were analyzed pure feedback control and feedback control with prediction of the field producing current component. The principles, control structures, simulation and experime...

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). IPMSM ́s 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 ma...
