To address the resonance issue of flexible loads driven by permanent magnet synchronous motors (PMSMs) in electric vehicles, the resonance suppression scheme based on speed feedback incremental compensation is adopted. Firstly, a high pass filter is utilized to effectively determine the resonance frequency point in the speed response. Then, for increasing the coefficient associated with vertical component in the electromagnetic torque and the damping coefficient in the system, the electromagnetic torque can be reasonably regulated by the negative feedback compensation according to the torque increment at the resonance frequency point. Thus, both the system stability and resonance suppression can be ensured. Following this, a speed feedback coefficient is introduced, which aims to increase the degree of freedom of the poles and even further improve the control performance. Finally, the feasibility of the method is validated by simulation.
