ABSTRACT:
A drive unit for controlling a motor includes a position feedback device and a velocity noise filter. The position feedback device is operable to generate a position signal relating to a position of the motor. The velocity noise filter is coupled to the position feedback device and operable to filter the position signal over a predetermined number of samples to generate a velocity feedback signal for the motor.
