the inputs of the formers 7, 8 of the decomposition coefficients are received.

The decomposition coefficient shapers compute the coefficient coefficients HI and PI of the orthogonal decomposition of the realizations x {/) and y (/). For example, L Herr can be chosen as the orthogonal basis.

Signals proportional to the coefficients of the decomposition of. and | 3i, are received in the majority device 9. At the same time, the four other inputs of the majority device are supplied with proportions, proportional mx, 8x - from the output of the input device about signal normalization and niy, d ,, - from the output of the input device 6 . At the same time, the sigpals proportional to the coefficients ai and Pb arrive at the first inputs of the threshold elements 15, 16 of the majority device, and the second inputs of the threshold elements receive the signals proportional to the bl- and bu from the outputs of the input devices.

The threshold element makes a comparison of the signals, the non-normal b.1- and yOy, with the signals that are proportional to uj and pi, the selection of stationary-severity in implementations X (t) well (/). For plots stacnonarpostn

the following inequalities are true

The coefficient y is chosen emlyridically depending on the smoothing interval t.

When simultaneously executing (3), the logical circuitry 17 gives permission for the switches 18 and 19 to feed the signals, pronoriopalpical fii and / pu, into the division unit 10. The division unit performs the calculation of the x x (t) and // stationary intervals (/) static gain

 about

Cnna, proportional to K, from the output of the dividing unit enters the device of Comparative 2, where it is compared with the required value of the CTE gain factor, which does not come from the output of the setting unit 1 of the Ssylenie factor. The result of the comparison, nronorionalpyn L / (., Enters the actuator 3, which, in accordance with the magnitude and sign of A / (changes the static gain KHii, of the gain of the system.

The system for managing a static coefficient is amplified, containing the first and second input devices for normalizing the sigal, connected to the first one with the input, and the second from the output: m of the control object; comparison device, the output of which is connected to the control object through an ispolnoe device, characterized in that, in order to broaden the field of application of the system in order to control the autonomy of its autonomy), it has There are two formulas 1) an expansion coefficient equation | and a majority device, the outputs of which are connected to the inputs of the division unit, and the inputs are connected to the corresponding outputs of the first and second input devices of the signal piping system, the first outputs of which are connected to the inputs of the majority device through the form. coefficients)
