result of action as it contains numerous SFU. If it could be possible to do it so that it enables actuating from one to all of SFU, depending on the need, the result of action would have as much gradation as many SFU is present in the system. The higher the required degree of accuracy, the more of minor gradations of the result of action should be available. Therefore, instead of one SFU with its extremely large scale result of action it is necessary to use such amount of SFU with minor result of action which sum is equal to the required maximum, while the accuracy of implementation of the goal is equal to the result of action of one SFU. However, composite SFU has no possibility to control the result of action as it has no the unit able of doing it. To deliver the result of action precisely equal to the preset one, it (the result of action) needs to be continually measured and measuring data compared with the task (with command, with "Database"). The "database" is a list of those due values ​​of result of action which the system should deliver depending on the magnitude of external influence and algorithm of the control block operation. The goal of the system is that each value of the measured external influence should be corresponded by strictly determined value of the result of action (due value). To this effect it is necessary "to see" (to measure) the result of action of the system to compare it to the appropriate/due result. And for this purpose the control block should have a "Y" receptor which can measure the result of action and there should be a communication/transmission link (reciprocal paths) through which the information from a "Y" receptor would pass to the analyzer-informant, where the result of this measurement should be compared with what should be/occur (with "database"). The control block of the system should compare external influence with the due value, whereas the due value should be compared with own result of action to see its conformity or discrepancy with the due value. Composite SFU still can compare external influence with eigen result of action, because it has DPC, whereas it can not any longer compare due value with the result of eigen action just because it does not have anything able of doing it (there are no appropriate elements). p> Simple control block (negative feedback - NF). In order for the control block of the system to "see" (to feel and measure) the result of action of the system, it should have a corresponding "Y" receptor at the outlet/exit point/of system and the communication link between it and a "Y" receptor (reciprocal path). The logic of operation of such control consists in that if the scale of the result of action is lager than that of the preset result it is necessary to reduce it, having activated smaller number of SFU, and if it is small-scale it is necessary to increase it by actuating larger number of SFU. For this reason such link is called negative. And as the informat...
