Torque Ripple Suppression Control for PM Motor Considering the Bandwidth of Torque Meter
IEEJ Transactions on Industry Applications, 2010 PM motor drive systems are widely used for industrial drives. However, PM motors basically produce the torque ripple due to the fluctuation of the magnetic field distribution. Dead time of the inverter, offset of sensors and current measurement errors lead to the torque ripple, too. The torque ripple leads vibration noises. In this paper, we proposed a
