    摘要: 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, wherein the first magnet is provided such that different poles are alternately arranged at an angle of 90° and the second magnet is provided such that different poles are alternately arranged at a predetermined angle, and a control unit wherein a first hall sensor is disposed in a rotational section of the first magnet to sense a change in polarity of the first magnet, and a second hall sensor and a third hall sensor are disposed in a rotational section of the second magnet to sense a change in polarity of the second magnet.
