The development of new control systems for complex technological facilities that are able of adequately responding to more dynamic and changing external and internal excitatory influences, is one of the main issue of the theory of automatic control. Therefore, it is important to create new automated control system that can provide the required accuracy of quality control. The structure of the control system, which maintains the adaptability characteristics in a wide range for the adjustment of various parameters in technological objects with variable parameters, is proposed and its efficiency is justified by modeling. A logical control algorithm for creating a control effect is provided.

“…As the mathematical model of an industrial process is usually a high order model, it is challenging to apply to controller design. It is preferable to reduce it to a first or second order transfer function, while retaining the main features of the controlled system [8]. In this paper, it is assumed that the circulation pipe is well adiabatic and has a uniform flow rate during the heating process.…”

The test equipment is used to measure the deformation of the shell of the phase change energy storage device during the melting and solidification of the phase change material and to monitor whether bulging occurs to ensure its structural safety. When the test device is used to simulate different orbit operating environments, due to its structure and process characteristics, this temperature control process has time lag problems, non-linear problems and various unknown interferences using conventional control methods. It is difficult to obtain satisfactory static and dynamic performance. To this end, a modified Smith prediction compensation control method is designed to improve the control speed and robustness by introducing a Smith predictor in the fuzzy PID control loop to compensate the time lag of the control in advance. Finally, MATLAB is used to program and simulate the system with the modified Smith prediction compensation control method, and the results show that the modified Smith prediction compensation control method is more superior compared with the traditional PID control method and fuzzy control method.

“…According to experts [3], the problems in the development and application of control systems that can implement the minimization of energy costs in rectification columns are primarily related to their always working under the influence of internal and external stimulating factors, nonlinearity and non-stationarity of their dynamic features. In this regard, a number of research works deal with the issue of developing an adaptive control system which Engineering meet the standard requirements of various oil fractions produced at any value of consumption and quality indicators of raw material in the technological facility of primary oil processing [4,5]. In a broad sense, adaptive control systems are the control systems that provide the obtaining of products with relatively stable quality indicators and meet the requirements regardless of the internal and external, controlled and uncontrolled stimulating influences that affect the technological facility as a whole [6].…”

As it is known, primary oil processing facilities are designed for the production of light-colored oil products and various oil fractions that meet modern requirements with their quality. The main equipment of these technological facilities are rectification columns operating under atmospheric and vacuum conditions, which perform the decomposition of crude oil and fuel oil into various product fractions. Generally, the quality indicators of product fractions produced in these columns are provided by stabilizing the temperature modes at certain points (plates) of these or rectification columns by regulating the irrigation consumption supplied to those plates. It should be noted that currently, in accordance with the requirements of the time, the design and development of new control systems that can adequately respond to more dynamic and variable external and internal stimulating influences for complex oil refining technological facilities is one of the main problems facing the automatic control theory. The paper is dedicated to the issue of developing a new automated control system that can provide the required accuracy in terms of quality management. As an adaptive control system, the purpose of such systems is to compensate in time for disturbance influences in the technological devices and to ensure the production of oil products with stable quality indicators, regardless of these influences. The purpose of study is to develop a control system that can meet the given requirements and ensure the produced products with relatively stable quality indicators, regardless of the controlled and uncontrolled exciting effects affecting the oil refinery technological complex. The principle of operation of this system is based not only on the compensation of disturbance influences but also on the calculation of new operation strategies depending on these effects. The development of new automated control system that is able to provide the necessary accuracy of quality control in the lack of information is relevant
