A method and apparatus for controlling regeneration for a motor (202). An instantaneous voltage provided by a power supply (205) to the motor (202) is identified using a voltage signal received from a voltage sensor (210). A new average voltage is computed for the motor using the instantaneous voltage (214), a previously computed average voltage (218), and a weight factor (220) for the instantaneous voltage. A difference (222) between the new average voltage and the instantaneous voltage is compared to a selected threshold (224) to determine whether a regeneration condition exists. Operation of the motor (202) is controlled such that a duty cycle of the motor does not decrease in response to a determination that the regeneration condition exists.
