基于霍尔位置传感器的电动汽车用永磁同步电机的控制

Controlling of Permanent Magnet Synchronous Motor in Electric Vehicle with Hall Position Sensors

介绍了采用低分辨率霍尔位置传感器估算转子角度和转速的基本原理,提出了在永磁同步电机(PMSM)中应用的一种转子角度慢校正控制方法,能有效减小电流的波动,利于电流的平滑控制。在基于数字信号控制器STM32F103RBT6的硬件平台上,实现正弦波矢量控制,角度慢校正的方法能有效抑制转矩脉动,电机运行平稳。

Using low-resolution hall position sensor to estimate the rotor angle and speed was introduced. A control method of rotor angle slowed correction was proposed, this method could effectively reduce the current fluctuations, which was conducive to the smooth control of the current. In the hardware platform based on the digital signal controller STM32F103RBT6, the sine wave vector control was realized. Slow angle correction method could effectively suppress the torque ripple, and the motor run smoothly.
