What Does Automation Control Do? Application Guide for Automation Controls


There are semi-automatic and full automation in automation control. Automation control is a kind of integrated control technology and theory of mechanical and electrical automation in the production fields such as modern industry, agriculture, and manufacturing.


Automation Control


1. The control principle of automatic control


Automatic control has semi-automatic and fully automatic.


For example: machines and equipment can be automated in accordance with the requirements and purposes of production; fully automatic people only need to act as operators to determine control requirements and procedures, and do not need to directly participate in the control technology of the production process; Participation of labor such as equipment, machinery, instruments or manual work.


Automation control technology is widely used in industry, agriculture, military, scientific research, transportation, commerce, medical care, service and family, etc. The use of automatic control can not only liberate people from heavy physical labor, some mental work, and harsh and dangerous working environments, but also expand human organ functions, greatly improve labor productivity, and enhance human ability to understand and transform the world. . Therefore, automatic control is an important condition and a significant symbol of the modernization of industry, agriculture, national defense and science and technology.


2. Application of automatic control


2.1 Process automation
Automatic control of chemical treatment of fluids or powders in petroleum refining and chemical industries. Generally, a process control system composed of detection instruments, regulators and computers is used to optimally control heating furnaces, distillation towers and other equipment or the entire factory. The main control methods used are feedback control, feedforward control and optimal control.


2.2 Mechanical Manufacturing Automation
This is the result of the combination of mechanization, electrification and automatic control, and the object of processing is discrete workpieces. Early mechanical manufacturing automation was stand-alone automation using mechanical or electrical components or a simple automatic production line. After the 1960s, due to the application of electronic computers, CNC machine tools, machining centers, robots, computer-aided design, computer-aided manufacturing, and automated warehouses appeared. Developed a flexible manufacturing system (FMS) suitable for multi-variety and small-batch production. The automated workshop based on the flexible manufacturing system, coupled with the automation of information management and production management, has emerged a factory automation control system using a computer integrated manufacturing system (CIMS).


2.3 Management automation
The automatic control of human, financial, material, production, office and other business management in factories or public institutions is a comprehensive technology with information processing as the core, involving electronic computers, communication systems and control and other disciplines. Generally, a local network composed of multiple computers with the ability to process large amounts of information at high speed and various terminals is used. Hyundai has developed a decision support system (DSS) on the basis of management information systems to provide alternative solutions for senior managers to make decisions.


3. Automatic control system


The automation control system refers to the system that can realize the automatic control task, which is composed of the controller and the control object.


3.1 The concept of automatic control system
Automatic control refers to the use of external equipment or devices to make a certain working state or parameter of a machine, equipment or production process automatically operate according to a predetermined law without the direct participation of people.


4. Features of automatic control


Automatic control is a technical measure that can automatically adjust, detect, and process machinery, equipment, and instruments, and automatically perform operations according to prescribed procedures or instructions. Its purpose is to increase output, improve quality, reduce cost and labor intensity, and ensure production safety.


4.1 Theory of Automatic Control System
Automated control is relative to the concept of manual control, which refers to the use of control devices to make the controlled object or process automatically run according to predetermined rules without the participation of anyone. The research of automatic control technology is beneficial to liberate human beings from complicated, dangerous and cumbersome working environment and greatly improve the control efficiency.


Automatic control is a branch of engineering science that deals with the automatic influence on a dynamic system using the principle of feedback to bring the output value close to our desired value. From a methodological point of view, it is based on the systems theory of mathematics. What we call automatic control today is a branch of cybernetics that arose in the middle of the twentieth century.
