The present invention relates to an actuator control apparatus which can perform a precise control until 0.005 mA, a resolution of 3000:1, when controlling a valve (V) by offsetting a backlash generated in a gear box (G) by making a drive unit (60) to drive a motor (M) by adding pulse amount, which is a backlash value of the gear box (G) until a point that a position value of a rotation gear (H) is changed, to a final operation signal of a micom (40) by counting up a pulse amount rotated in the opposite direction of a straight rotation direction of the motor (M) by the drive unit (60) based on a current position value of the rotation gear (H) after a normal rotation or a reverse rotation of the motor (M). |
