Human activities in modern systems special purpose is characterized by increased complexity, reduced footprint for that time and the aggravation of moral and psychological factors associated with increasing responsibility for decisions and actions.

An urgent task is to transfer functions and tasks that are solved by a person to technical systems that can, if not completely replace a person, then facilitate his work. Such systems are artificial intelligence systems and, in particular, expert systems.

The article analyzes the features of solving applied problems through the use of expert systems that work in real time, and defines the principles of interaction of expert systems of special-purpose automated control systems. The main factors influencing the solution of such tasks are: no known probability dependencies; different reliability of information received for analysis; complexity of models representing the subject area; qualitative character of the description of many features; the number of source data that is not constant from time to time; inconsistency of data from different sources.

This situation forces us to use artificial intelligence methods to solve the corresponding problems.

It is determined that the main tasks can be defined as identification, sorting, interpretation, prediction, planning, observation, decision-making, evaluation, evaluation, diagnostics, debugging, management.

The basic principles of interaction of expert systems with automated control system elements in conditions of limited time resource are defined. The main ones can be described using the communicative function, semantic function, and pragmatic function.

Such a complex nature of interaction between the ES and the control system determines the requirements that the implementation of the interface must be organized by special hardware and software, which can be considered as an integral part of the realtime ES.
