Abstract
A control device for an actuator learns a reference position of a shaft when the operation of the engine of a vehicle is not obstructed in a period during which the engine is operating, and performs feedback control by using the reference position learned thereby in such a way that the position of the shaft detected by a position sensor gets close to a target position.
