Abstract:
Disclosed is an apparatus for controlling an actuator that controls opening and closing of an intake valve. The apparatus includes an input shaft connected to a motor and an output shaft rotatable in conjunction with the input shaft, a magnet unit including a first magnet and a second magnet provided on concentric circles, the first magnet provided such that different poles are alternately arranged at an angle of 90° and the second magnet provided such that different poles are alternately arranged at a predetermined angle, and a control unit, wherein a change in polarities of the first and second magnets are sensed.
