Abstract

This invention relates to the field of Self-Tuning Systems with Signal Tuning. The aim of the invention is to improve the accuracy of system tuning. This goal is achieved by connecting the second adder in series with the reference model, the second input of which is connected to the controller output, and the output of the adder is connected to the control unit consisting of the series-connected dividing unit, the delaying unit and the multiplying unit. 1 il.

Description

The invention relates to automatic regulation, and more specifically to the design of self-adjusting control systems using the signal tuning method.

The purpose of the invention is to improve the accuracy of system tuning.

The drawing shows a block diagram of the system.

The system contains an input sensor 1, a first adder 2, a regulator 3, a control object 4, a reference model 5, a second adder 6, a division unit 7, a delay unit 8 and a multiplication unit 9.

The transfer function of a closed system can be written as

TF,

(one)

De 1 - the desired transfer function - deviation of the transfer function from the desired one (including external disturbances).

The signal at the output of the control system will be

R . . ,

where Y is the signal at the output of the control system, f - -.

F is the signal at the control system input.

For the system to operate, it is necessary to submit an additional signal U, then the output signal will look like

Since kickoff can be taken as the initial time point, then the offset (2 is valid for the entire time axis.

The control system operates as follows.

The input signal is applied to the reference model 5 and to the tunable control system. The second adder 6 is supplied with a signal from the outputs of the controller 3 and the reference model 5. At the output of the second adder 6, a signal is generated that is proportional to the deviation of the real output signal from the signal coming from the output of the reference model 5.

- The delay block 8 and the multiplication block 9 realize the desired tuning signal. Invention A self-adjusting control system with a signal setting, containing ps5, a well-connected input effect sensor, a first adder and a regulator connected by the output to the INPUT of the control object, and a reference model, the input of which is connected to the output of the sensor, the input effect, and output - with the first input of the second sutmatmator, the second input of which is connected to the output of the regulator and the second input of the first adder, about 45 liters per hour so that, in order to improve the accuracy of system tuning, itelno administered serially connected dividing unit, and delay unit multiplier 50 whose output is connected to the third input of the first adder, and the second input to the output of the second adder, the output of the input action sensor is connected to the first input of the divider unit, the second input of which is connected to the output of the regulator.
