Journal of power electronics and power systemsSummary: The minimization of speed ripple of the permanent magnet synchronous motors (PMSM) in low speed range becomes a major problem while applying the PMSM to refrigerant system. Earlier, an iterative learning controller was applied in conjunction with the conventional proportional integral (PI) speed controller to minimize the speed ripple. Here, a frequency variable resonance controller is applied in conjunction with the conventional proportional integral speed controller as a PI-RES controller, which provides the reference torque current. Compensation torque current generated by the resonant controller, together with the main reference current is utilized to minimize speed ripple. The results are verified through simulation.
