摘要：
There is inherent 6-th harmonic in the position estimation of the traditional pulse high frequency voltage injection method. Although the improved algorithm based on twice anticlockwise angular speed (TAAS) can suppress the 6-th harmonic, the torque harmonics are rich and the speed ripples are large. To suppress the 6-th harmonic in the estimated position and reduce the torque ripple at the same time, a rotating sythesis vector (RSV) based high frequency pulse voltage injection method for the sensorless control of the flux-switching permanent magnet machine (FSPMM) was proposed. First, the rotating synthesis vector make the difference between the estimated d-axis and q-axis be 90 degrees, so that there is no 6-th harmonic in the input of PI regulator, solving the problem of 6-th harmonic. Second, the length and the rotating angular frequency relative to d-axis of the rotating synthesis vector were fixed, solving the problems of rich torque harmonics and large speed ripples in the TAAS algorithm. Therefore, the proposed method improves the accuracy of position estimation and speed control, which is verified on a FSPMM. ©2022 Chin.Soc.for Elec.Eng.
