Abstract
PURPOSE: To shorten the phase drawing time and prevent hunting due to excessive gain by varying the phase loop gain according to the magnetitude of phase error.
CONSTITUTION: In an phase comparison circuit 1, each phase of the standard signals A and the detected phase signals B of a controlled apparatus 4 is compared, and after proper compensation is applied in a phase compensation circuit 2, both signals are sent to a gain variable circuit 5. Into the gain variable circuit 5, also the error signals C are sent, and when the error signal is large, gain is increased, and when small, gain is reduced, and hunting is prevented. The output of the gain variable circuit 5 is amplified by a class "A" amplifying circuit 3 and drives controlled apparatuses 4 such as revolution bodies.
