Abstract
A motor is controlled to regulate the speed of a vehicle sliding door whose movement and speed are monitored. The motor control voltage is incrementally adjusted in direction to reduce a sensed speed error only if the door has moved a required distance while the door speed has been continuously outside of the desired speed range since the last incremental adjustment to the control voltage.
