| 摘 要： | 由于永磁同步电机(PMSM)具有体积小、功率密度、效率及功率因数高等特点,目前在电动汽车驱动系统中具有较高的应用价值.针对电动汽车用PMSM基速以上弱磁控制时存在的电流调节器饱和、不可控问题,设计了基于转子磁场定向带电压外环控制的电流超前角弱磁控制方法,实现了基速以下恒转矩调速和基速以上恒功率弱磁控制,以及两种工作模式...

| Abstract: | Permanent manet synchronous motor(PMSM) has many advantages in the motor driving system of electrical vehicle because of its excellent performances,such as small cubage,great power density and high efficiency.This pa-per describes a novel flux-weakening control method for the PMSM.It is implemented based on the outer voltage regu-lation loop which regulates the phase angle of current leading EMF in order to prevent the saturation and uncontrol-lable status of the current regulator.Based on the d,q mathemati... |
