Abstract
Methods and apparatus are provided for reducing torque ripple in a permanent magnet motor system comprising a permanent magnet motor coupled to an inverter. The method comprises the steps of receiving a torque command, generating a torque ripple reduction signal in response to the torque command, modifying operational control signals in response to the torque ripple reduction signal to generate reduced ripple operational control signals, and providing the reduced ripple operational control signals to the inverter for control of the permanent magnet motor.
