| Abstract:Aiming at the problem of electromagnetic torque ripple of permanent magnet motor caused by the magnetic field of air-gap and the nonlinearity of the inverter during the operation of the permanent magnet synchronous motor. A method of suppressing torque ripple of permanent magnet motor based on resonant regulator and harmonic injection is proposed. The mathematical model of the harmonics generated during the operation of the permanent magnet motor is analyzed. The feed forward control section based on the resonant regulator，the harmonic extraction algorithm and the harmonic wave injection algorithm are designed. Finally，simulation analysis was performed on the Simulink simulation experiment platform. It successfully suppressed the current harmonic content in the motor，reduced the distortion of the current，and improved the smoothness of the output torque of the motor. The correctness and feasibility of the feedforward control and harmonic injection suppression algorithm of the resonant regulator are verified. |
