摘要：
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. © 2022 Chinese Machine Press.
