摘　　要：在电动助力车用永磁同步电机(PMSM)控制系统中,针对PMSM在正常运行过程中发生霍尔位置传感器安装位置偏移的问题,提出基于带通频率跟踪滤波器的电机转子位置与速度估算方法。该算法将三相霍尔信号通过坐标变换转换为霍尔矢量,通过带通频率跟踪滤波器与锁相环提取霍尔矢量中的电机转子位置信息,以实现在霍尔位置传感器安装位置偏移情况下,对永磁同步电机转子位置与速度信息的正确估算。通过实验验证,该算法有效地减小了在霍尔位置传感器发生安装位置偏移时电机转速与电流的波动,提高了控制系统的可靠性和稳定性。In the permanent magnet synchronous motor(PMSM)control system for electric mopeds,method for estimating the position and speed of the motor rotor based on the band-pass frequency tracking filter are proposed to solve the problem of the deviation of the installation position of the Hall position sensor.The algorithm converts the three-phase Hall signal into a Hall vector through the coordinate transformation,and extracts the rotor position information of the motor in the Hall vector via a band-pass frequency tracking filter and a phase-locked loop,so as to the correct estimation of the rotor position and speed information of the permanent magnet synchronous motor has been realized on the condition of the installation position offset of the Hall position sensor.Through experimental verification,the algorithm effectively reduces the fluctuation of the motor speed and current when the Hall position sensor is installed at a position offset,and improves the reliability and stability of the control system.
