电动汽车永磁同步电机的转子位置检测和驱动控制策略

摘要

The key control problem of permanent magnet synchronous motor for electric vehicle is rotor position detection and drive control.According to the physical and mathematical model of permanent magnet synchronous motor (PMSM), this paper puts forward a method of rotor position detection by detecting and estimating the rotor position of PMSM with position-related electrical signals, and adopts vector control technology to drive the control strategy.%电动汽车用永磁同步电机关键控制问题是转子位置检测和驱动控制,本文根据永磁同步电机的物理与数学模型,提出了检测与位置相关电信号来估算电机转子位置的方法进行转子位置检测的策略,采用矢量控制技术驱动控制策略.
