Description

The invention relates to the field of astronomical technology and can be used in controlling the guidance of radio telescopes, as well as chemi control objects, which are connected to actuators through elastic connections;

The aim of the invention is to increase the speed and reduce the oscillation of the system.

The drawing shows a diagram of the system.

The system includes an actuator 1j electric motor 2, an adjustment object 3, a second and first tachogenerators 4 and 5, a summing power amplifier 6, an adder 7, a current sensor 8, an adjusting unit 9, a setting unit 10,

The actuator 1 includes an electric motor 2, a summing current amplifier 6 and a current sensor 8.

The system works in the following way.

The setting unit 10 generates at its output a signal X., which is fed to the first input of the control unit, to the second input of which a signal x is received from the output of the second tachogenerator 5, and to the third input - a signal x from the output of the adder 7. At the output of the regulating unit 9 signal Ua

where K, Kq, K are the gain factors for the first, second, and third inputs of the regulating unit 9, W (p) is the transmission coefficient of the regulator, the whole of unit 9.

The indicated coefficients in the general case can have different (i.e., different from each other) values both in absolute value and in sign. In the particular case koef4

The factors K., K can be positive, the coefficient K, be negative, and the ratio of the transmissions W (p) equals W (p) + /.9 Dy P where 9, the coefficients are proportional | T, the T is a constant of integration block 9.

30 and output shafts of the adjustment object 3. Output signals x. and Xj of the second and first tachogenerators 4 and 5 are fed to the inputs of the adder 7.,

At the output of the adder 7, a signal x of the form is formed:

Hu +.

where Kj and Ku are the gain factors for the first and second inputs of the adder 7.

These coefficients in the general case may have different (i.e., different from each other) values

both in magnitude and in sign. In the particular case, the coefficients K, K7 may have the values: k -1. K.1.

The output signal x is supplied to the 50th third input of the regulating unit -9. In the future, the system works in a similar way.
