PROBLEM TO BE SOLVED: To provide an actuator controller which consists of a small number of mechanical components and can make the device small-sized and stably perform high-precision detection. SOLUTION: The controller which controls an actuator 10 having a rotary part with an external command value S0 and the rotation detection value of the actuator 10 is equipped with rotational angle detection means 2 and 3 which are attached to the actuator 10 and detect the rotational angle of the actuator 10, a rotational frequency counter 3a which counts up or down by '1' in consideration of the rotating direction of the actuator 10 each time the rotational angle detected by the rotational angle detecting means 2 and 3 reach 0 deg., and means 4 and 3 which obtain rotation detection values SB and SD according to the rotational angle detected by the rotational angle detecting means 2 and 3 and the rotational frequency counted by the rotational frequency counter 3a. |
