Pa 12 and the second output of the adder 14 are fed to three inputs of the key management unit 44, the signal from the first output goes to the control inputs to the bales 33, 35, 37, 39 and 41, and the signal from the second output goes to the control inputs of the calls 34, 36, 38, 40 and 42.

The conditions for using object and sensor models in fast and slow self-tuning circuits are explained as follows.

The first condition: - means that the first model that is in the slow self-tuning loop is not configured, the second model that is in the fast self-tuning loop is also not configured and therefore there are no reasons (conditions) for switching the models, although; It is possible to replace the m ;; sharing in the main contour of the recovery;

the second condition:, t -2: s, e b --- means that the model. finding and., and c in the slow self-tuning loop, is set up and independent of wellness; -the RV and the short-term state of the state (for example, switching of the light channels) is not: 1 it is expedient, because the regulation is implemented ;

the third condition:,, - means that the model in the fast self-tuning loop is configured (). contour error regulator-; an - less than specified () HacTpoeiiHVK; the model can be included in the main circuit:; instead of non-inflating}; Noah () without introducing and disturbing the main control loop:

The fourth condition:,, - means that although the unit in the fast self-tuning loop is configured () and the model in the main control loop (in the slow self-tuning loop) is not configured, switching is impractical, as with the perturbation from switching to one; she will call iiepepei -regulation regulable-io-o pa) meter, 1 de K, t 2 - mismatch between the set and model values of thickness, respectively, for the first and second models of the object:

a, b - specified error limits.

At the beginning of the system, when the models are not configured (,,), a control is generated; 1 signal is generated at the first output of the key management lock box 44 and the keys 33, 35, 37, 39 and 41 are opened.

In this case, the signal from the object 7 and the signal from the model 17 of the object through the key 33 arrive at the inputs of the multiplication unit 23 and the power factor unit 27 (|:).

The setting of the object model is described in the main invention. The coefficient block 27 implements the coefficient of the slow self-tuning loop. The output of the block of 27 coefficients through the public key

37 is fed to the first input of the pickup unit 29 and then the output signal from this block is multiplied with the signal from the output of the power converter 6. From the output of the multiplication unit 24, the correction signal is fed to the second input of the thickness sensor model 19. During the operation of the system, the model 17 of the object is adjusted and its output signals via the public key 35 are used in the main control loop. The parameters of the coefficient block 27 are selected so that in the main system control loop the transient process takes place without overshoot (or with a specified overshoot). However, under these conditions, the adjustment of the object model 17 occurs slowly. At the same time, the signals from the output of the coating thickness sensor 8 and the delay unit 22 are transformed by the adder 14, the multiplication unit 25 and the coefficient unit 28 (realizes the coefficient of the fast self-tuning) and is fed to the input of the unit 30 integoirno; ,; which, together with the input signal of the power converter 6, is fed to the inputs of the multiplication unit 26, and from the output of the last corrector, the right signal is fed to the input of the model 20 of the tolce sensor |, yin coating. This signal arrives at the second input of the model 20 of the coating thickness sensor and corrects 3bixo; iiioi: the signal of the object model 18.

The object model 18 is tuned during system operation, but much faster than the first due to the appropriate selection of parameters of the coefficient block 28. The output signal of model 18 of the object and model 20 of the thickness gauge is not used from the main control loop of cncTe vibi, since the key 36 is closed and the model setting rate does not contribute to the system.

If the condition:,, (i.e., the second model is configured, the first is not present and the adjustment error is static or tends to zero), in the key management unit 44 a control signal is generated at the second output and therefore the keys are even-numbered from the fourth) open, and from the odd ones (starting from the third) close.

In this case, the output signals of the object model 18 and the coating thickness sensor model 20 (without delay and delay) are connected via the open key 36 via the open key 32 to the second input of the adder 10, i.e., the adjusted object model 18 is used in the main control loop. The object model 7 and the coating thickness sensor model 19 (together with the lag unit 21) are connected with keys to the fast self-tuning circuit (adder 14, multiplication unit 25 and coefficient unit 28), where the tuning of the object model 17 continues. Thus, model 17 turns

/ lach n is fast self-tuning and continues to be adjusted, and the adjustment in the system is carried out according to the configured model 18 of the object.

In the event of a change in conditions, a reverse switching of the models may occur.

A simulation for a specific system with a PID controller showed that at, 2 (see Fig. 5) the overshoot in the interval is insignificant (is in the 5% zone), however, the tuning of the coefficient continues for UT (see Fig . 6). Moreover, if the subsequent disturbance occurred in the range of up to 7-8 tons, then the first release of the controlled parameter after the application of the disturbance is significant, since the model has not yet been tuned.

At the same time, i.e., when the model is tuned in the slow self-tuning loop, the second model is tuned in the fast self-tuning loop, without outputting signals from the model in OCHOBHOI; regulation, 1

Thus, using a model of an object with slow self-tuning in the main control loop does not cause overshoot. After setting up the second model in the fast self-tuning loop, this model is switched to the first one (to the main control loop), the first is switched to the fast self-tuning loop and continues to be adjusted, as these operations are performed at higher levels, the following conditions :

In a system without a second mode and a fast self | | contour, settings with a tuned model begin with Ute. ten
