PROBLEM TO BE SOLVED: To restrict overcurrent through an electric actuator in setting an initial position of the electric actuator by applying a movable member to a stopper member, and reduce load added to the movable member. SOLUTION: A control device main body 1 to control an intake door actuator 10B in which position control to a movable part is carried out based on a position signal from a position signal generating part 10Ba drives an intake door actuator 10B with a first duty ratio D1 while an intake door 10A driven by the movable part is between a position before a first position by prescribed quantity 1αwhere it is applied to the stopper member 100A provided at one end of a movable range of the movable part and the first position, and drives it with a second duty ratio D2 that is smaller than the first duty ratio while the intake door 10A is between the first position and a second position where it stops. The position of the intake door actuator 10B detected with the second position is stored as an initial position. COPYRIGHT: (C)2007,JPO&INPIT
