Summary:In a retroactive control circuit for the coil current of an electromechanical adjuster, the control voltage acts by way of a buffer operational amplifier (O1), upon a second operational amplifier (O2) which is wired as an integrating controller and whose negative input is connected both to the negative input of a third operational amplifier (O3), wired as a comparator, and also to a resistor (R16) located in the output circuit of a current-imaging circuit. A fourth operational amplifier (O4), wired as an oscillator, supplies to the positive input of the integrating controller (O2) a square-wave voltage at a frequency to which the adjuster cannot respond, and which has an amplitude slightly greater than the hysteresis.
