ABSTRACT:
An automatic loop gain control apparatus in a servo control apparatus of a closed loop arrangement which positions a control object with respect to a reference. The apparatus includes an adder for adding a reference signal of a predetermined frequency to a control signal in the closed loop, a first detector for detecting a peak value of predetermined frequency components of the control signal in a state before the control signal is input to the adder at every predetermined cycle, a second detector for detecting a peak value of predetermined frequency components of an output output from the adder at every predetermined cycle, and a digital signal processor for performing a digital computation using the peak value detected by the first detector and the peak value detected by the second detector and for adjusting the gain of the control loop on the basis of the result of the computation.
