Abstract :
PM motor drives are widely used for high performance servo applications. However, PM motor has imperfect sinusoidal flux distribution which causes harmonic current. Dead time of the inverter and current measurement error lead to harmonic current, too. In this paper, we propose harmonic current suppression based on perfect tracking control. Finally, we show the advantages of proposed method by simulations and experiments.
