Beschreibung
Zusammenfassung:	A motor loss controller (101) configured to band-shift a motor frequency signal by a multiple of a fundamental frequency into a parsed sine component and a cosine component and multiply a feedback signal (75) by each of the parsed sine component and the cosine component; perform integral control of a control value band-shifted sine component and a control value band-shifted cosine component, wherein the performing integral control is configured to at least one of eliminate or reduce a disturbance on an output of the motor loss controller by rejecting a DC disturbance in a band-shifted control value; inverse band-shift the sine component back to its original band; inverse band-shift the cosine component back to its original band; and sum the inverse band-shifted sine component and the inverse band-shifted cosine component together to result in a controller output (95).
