PROBLEM TO BE SOLVED: To provide an actuator control circuit capable of extending the response frequency range of a transmission characteristics of a control system and accurately executing a quick response by expanding a gain characteristics to a high band. SOLUTION: When an actuator 1 is connected to a sensor 4 for outputting a rotational angleθand detecting the angleθ, the actuator control circuit controls the rotational angleθ. The control circuit is provided with an amplifier 5 for amplifying an output signal from the sensor 4, and error adder 6 for dividing a command signal 9 for specifying the rotational angleθas a required angle and an output from the amplifier 5 into a proportional component and a differential component and amplifying respective components, and a driving circuit 8 for driving the actuator 1 based on an output from the error adder 6 constituted so that the command signal 9 are added to the adder 6 as quite the same components as the proportional and differential components to control the rotational angleθ. Thereby the response frequency range of the transmission characteristics of the control system is extended and a quick, accurate response is realized through extension of the gain characteristics up to a high band.
