Abstract：In the permanent magnet synchronous motor (PMSM) drives, periodic disturbance torques, caused by non-ideal factors like dead time effect, flux harmonics and current sampling errors, can lead to speed ripples. To solve this problem, this paper proposed a control strategy of speed ripple minimization where the proportional gains of the main order speed ripple components were compensated. Firstly, this strategy estimated the main order speed ripple components by Kalman filter, and embedded these estimated components in forward channel of speed loop by paralleling them with the PI controller. Then, according to attenuation degree of periodic disturbance torques, the values of proportional gain compensation corresponding to these speed ripple components were selected. Thus these periodic disturbance torques were suppressed. The experimental results show that the proposed strategy can efficiently improve the steady-state performance of the PMSM drives.
