摘　　要：传统脉振高频电压注入法的辨识位置中存在着固有的六次谐波;改进的逆二倍频坐标算法虽然可以抑制六次谐波,但是转矩谐波含量丰富,转速波动较大。为了抑制辨识位置中的六次谐波并同时减小转矩脉动,提出一种基于旋转综合矢量脉振高频电压注入的永磁磁通切换电机无位置传感器控制方法,首先,旋转综合矢量对应的估计d轴和估计q轴上的高频电压信号相差90°,使得进入PI调节器的信号中不存在六次谐波,解决了传统脉振高频电压注入方法中存在的六次谐波干扰问题;其次,旋转综合矢量长度固定,且相对于d轴的旋转角频率固定,解决了逆二倍频坐标算法中存在的转矩脉动谐波多、转速波动大的问题。因此,该方法同时提高了系统的位置辨识精度和转速控制精度。在一台磁通切换电机系统平台上进行实验验证,实验结果表明该方法能同时提高转子位置辨识的精度,并减小转速的波动。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 90degrees,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.
