Abstract
A method and apparatus for controlling regeneration for a motor. An instantaneous voltage provided by a power supply to the motor is identified using a voltage signal received from a voltage sensor. A new average voltage is computed for the motor using the instantaneous voltage, a previously computed average voltage, and a weight factor for the instantaneous voltage. A difference between the new average voltage and the instantaneous voltage is compared to a selected threshold to determine whether a regeneration condition exists. Operation of the motor is controlled such that a duty cycle of the motor does not decrease in response to a determination that the regeneration condition exists.
