PROBLEM TO BE SOLVED: To provide an actuator control device which is improved in confinement detecting accuracy by correcting rotational speed data by using a new time constant, according to the magnitude of vibrations. SOLUTION: The actuator control device 1 is comprised of two rotational signal generating means 8, 9, an output shaft rotational speed calculating block 14, and an integral correcting block 17. The rotational signal generating means 8, 9 each generate a rotational signal according to rotation of an armature shaft 5a of a motor 5. The output shaft rotational speed calculating block 14 calculates the rotational speed data by estimating the rotational speed of an output shaft 7, based on the rotational signals generated by the rotational signal generating means 8, 9. The integral correcting block 17 compares a latest value of the rotational speed data with a value of the rotational speed data obtained before predetermined minutes, and if the difference between the two values exceeds a predetermined value, the integral correcting block 17 carries out calculation of new corrected rotational speed data which is referred to when determination as to pinching is executed.
