With the consideration of the DC‐link voltage fluctuation, the motor output torque contains a large number of fluctuating components, which may trigger electromechanical coupling resonance (EMCR) and deteriorate the system control performance. In order to solve this problem, the model of the electromechanical coupled system is established, and the ...
