The intensive development of information technologies with a high degree of autonomy requires the development of autonomous management systems for optimal management. This issue is especially acute for critical infrastructure objects that have been proven to be affected by extreme external factors and impacts. It is proposed to consider the management process as management in a system with incomplete a priori information about the managed process. The process of managing which changes as information accumulates and is used to improve the operation of the entire security system in general. An identification approach to the synthesis of indirect adaptive control is used, which consists in specifying the model of the object during the control process. On the basis of the refined model, a safety control signal of the object is produced. The model of the object needs clarification because the system is constantly affected by external uncontrolled influences. The difference between the proposed method and the existing ones is that it offers a method of building a robust control system that allows to compensate for unknown disturbances with a certain accuracy in the required time. At the same time, by selecting the parameters of the closed system, it is possible to make the error and time values sufficiently small.
A simulation of the operation of the security management system was carried out, the results of which proved that the quality of transient processes does not depend on disturbances that affect both the nature of the behavior of the solution of the differential equation describing the critical infrastructure object and its structure. Transient processes, first of all, depend on the initial conditions of the object model and the parameters of the control system. And this means that if in the process of designing the security system, the initial conditions are correctly set and the changes (including uncontrolled) of the parameters of the system's functioning are properly monitored, it is possible to ensure the stable and safe operation of the facility over time.
