基于幅值-相位的最优电压谐波注入以实现表贴式永磁同步电机速度谐波最小化

Low torque ripple level is the prerequisite for surface-mounted permanent magnet synchronous machines to maintain control accuracy and speed stability. Since the speed harmonic's amplitude is proportional to the torque harmonic's amplitude, torque ripple can be reduced by speed harmonic minimization. Harmonic injection method is a practical speed harmonic minimization method. But current harmonic ...
