Abstract
PURPOSE: To obtain a stabilized high control characteristic in all ranges of actuation, by means of keeping the loop gain of the control system always at a constant even whatever rotation angle degree of an oscillation frame.
CONSTITUTION: An input signal Es is compared and amplified with a feedback signal Ef by a servo-amplitude 14 and becomes to a deviation signal Ed, and then is multiplied to a compensating signal Ec from a gain compensation operator 16 by a multiplying operator 15, and becomes to a control signal Ei, and drives an actuator 11 by means of being sent to a servo-valve 13, thereby an oscillation frame 10 is rotated. Accordingly, the loop gain is always kept at a constant even when the oscillation frame 10 may be present at a whatever rotation angle, by means of setting the rotation angle, and of adding only to the servo-amplitude 14 as the input signal Es, thereby the acculate positioning control can be effected by means of oscillating the oscillation frame 10 by follow-uping to the input signal Es with rapidness and certainty.
