Analysis of Effective Control Strategy for IPMSM Driven by Electric Vehicles

Abstract

Field oriented control strategy for IPMSM for electric vehicle is analyzed considering the different operation conditions of elective vehicle. Maximum torque/current control and flux weakening control strategy based on voltage feedback compensation for demagnetizing current are adopted for IPMSM and SVPWM technology establishes motor control system. The Venucia Chenfeng 2014 version Lingfeng electric vehicle is the study subject carrier, ACR and ASR double closed-loop control used for simulation analysis and illustrate that this control system applied to electric vehicle drive system has small torque ripple and good static and dynamic response characteristics.
