Analysis And Solving The Problem Of Synthesis Of An Automatic Control System For A Tube Furnace

Abstract

It is known that the oil refining industry is considered one of the leading sectors of the national economy. The primary oil refining units is the main technological complexes of this industry. The purpose of these facilities is to ensure the production of a wide range of high quality petroleum products from crude oil. The requirements for quality indicators of various petroleum products produced at these technological facilities require the creation of more modern and advanced control systems.

Tube furnaces are one of the main technological devices in technological complexes of primary oil refining. The fulfillment of the given criterion of solving the issues of controlimg technological objects directly depends on the performance of control systems at the local level. From this point of view temperature control in tube furnaces is a topical issue.

In order for automatic control systems (ACS) to work properly, they must first of all be stable.  It must have such properties that the dynamic processes emerging in the system as a result of any non-zero initial conditions can gradually pass into a stationary state. After providing the sustainability requirements, the systems must meet the quality requirements; which is determined by a number of indicators characterizing the dynamic regime. In other words, the dynamic characteristics of the ACS should be investigated. To solve the problem, the issue of optimal tuning of controllers that are part of automatic control systems is considered, the stability of control systems is established and the parameters of the quality of trancient response of ACS is determined.

İn this paper the dynamic characteristics of the control object has been studied without disturbing the normal operating modes of the technological unit in order to find the quality parameters of the ACS
