Control method for IPMSM based on perfect tracking control and PWM hold model in overmodulation range

Abstract

Interior permanent magnet synchronous motors (IPMSMs) are employed for drive motors of electric and hybrid vehicles. Therefore, the control method in overmodulation range of inverter is important for fast torque response and expanding operation range of IPMSM. In this paper, the control methods based on perfect tracking control and PWM hold model are proposed in overmodulation range. The proposed methods do not need to switch controllers in overmodulation range. One of the proposed methods simultaneously prevents windup phemonemon and voltage saturation which is caused by harmonic current with PWM hold model. Finally, simulations and experiments are performed to show the advantages of the proposed methods.
