The device works as follows.

The inputs 8 and 9 of the device are supplied with independent variables with voltages U and U, respectively. The input signal with voltage U is fed to one of the inputs of comparison unit 1, the output signal of control unit 2 with controlled gain Uftwuln. The difference of the input signals at the output of the comparison unit 1 is a control signal. The change in the voltage of the output signal of the comparison unit 1 is higher. change4

This leads to a change in the intensity of the optical energy emitted by electric converters 7f 7, which post to the control inputs of the respective blocks of 24–2 g with a controlled transmission coefficient. If we consider that the transfer coefficient of the nth block with controlled transfer ratio in antiphase with the magnitude and polarity of the change in the input voltage of the comparison unit 1, then any difference between the input voltages of the comparison circuit leads to such a change in the transfer ratio of the nth control unit by the eight transmission coefficient, that after the transients in the closed circuit of automatic regulation formed by elements 6, 7 and 2 and the comparison unit 1, the state of dynamic equilibrium is automatically established, At which the input voltages of the comparison unit 1 are ensured:
