INVARIANCE OF THE MANAGEMENT SYSTEM OF A SPECIAL PURPOSE INFORMATION COMMUNICATION NETWORK UNDER THE CONDITIONS OF INCOMPLETE PRIOR INFORMATION

Abstract

The emergence of new, scientifically based advanced approaches to the construction and operation of a special-purpose information communication network, the development of modern secure communication technologies based on them made it possible to create a sufficiently effective and, at the same time, sufficiently extensive structure of the constituent elements of such a network. At the same time, special purpose information communication networks are emerging, individual elements of which can be built on the basis of various advanced technologies. In such conditions, a new scientific problem arises to ensure the invariance of the system of protected ICMSP in conditions of incomplete a priori information. The article presents the functional dependence of the invariance of the special purpose information communication network control system under the condition of incomplete a priori information. A disturbance management algorithm has been developed and proposed, and the reasonable feasibility of its use when introducing intentional disturbances has been substantiated. It is shown that this method can be considered as a way of controlling the system when summing the functions according to the control influence. The conditions for ensuring the invariance of control systems are given and the necessary mathematical expressions are given. Provision of an invariant control system under the influence of incomplete a priori information in the article is reduced to the well-known problem of signal reproduction in the presence of interference. Which is proposed to be solved by the criterion of the minimum of the error function. It is shown that in the case of random external influences, with the help of the introduction of previous distorting functions, it is possible to correct the signal by a value that coincides with the mathematical expectation of the error. Obtaining an invariant system in the "emergency" mode is reduced to the well-known problem of signal reproduction in the presence of disturbances, which is solved according to the minimum error function criterion. It should be noted that in this case, with the help of preliminary distortion, under random influences, it is possible to correct the signal by a value that coincides with the mathematical expectation of the error.
