Harmonic Current Suppression for PMSM by Repetitive Perfect Tracking Control
IEEJ Transactions on Industry Applications, 2008 AbstractPM motor drives are widely used for high‐performance servo applications. However, the PM motor has an imperfect sinusoidal flux distribution which causes harmonic currents. Inverter dead time and current measurement error also lead to harmonic currents. The repetitive control method has been applied to current suppression.
