The composite functional statistical criterion for evaluating the effectiveness of the automatic control process and system

Abstract

The process of managing and controlling equipment is a broader concept than data transmission. It includes collecting the information about the controlled parameters, transferring the information, its processing, the development of control actions and their transfer to the object in order to bring the controlled parameters back to normal. These tasks are solved by the control and monitoring system. Modern ACMS have not only a larger number of elements, but also a more complex internal structure. Even if all elements of ACMS function are in a reliable way in the process of its operation, the performance of the task assigned to the system cannot be treated as a reliable event. One of the essential features of ACMS is that they are meant to improve the quality of the controlled objects. To quantify the quality of complex systems, effectiveness indicators are used. Indicators of the quality of the system performance of the assigned functions are called the effectiveness of system operation or simply effectiveness. The main idea of evaluating the effectiveness of ACMS is to get the opportunity to compare systems that are identical in purpose, even if they differ from each other in the principles of design and operation. There are certain connections between the individual elements of ACMS, the system as a whole and the controlled object through which they interact with each other. From the point of view of evaluating ACMS effectiveness, the information content of these links is crucial, since the processes of automatic control, for example, in the field of electrical energy production and distribution, are carried out on the basis of information received about the controlled object.
