PROBLEM TO BE SOLVED: To accurately control a rotation angle of a synchronous link by eliminating force-fighting between first and second actuators by using a two-servo valve actuator control device.SOLUTION: The displacement of a piston 7 is detected for a first actuator 5, the first actuator 5 is controlled by feedback control, forces generated at both the first and second actuators 4, 5 are measured for the second actuator 4, a position control command value is corrected by imbalance amounts of the forces, the second actuator 4 is controlled by using a difference between a displacement position of the first actuator 5 and a feedback value, and thus force-fighting is avoided, and the rotation angle of the synchronous link 2 is accurately controlled. |
