automatic control technology is one of the fastest developing and most influential technologies in the 20th century and one of the most important high technologies in the 21st century
automatic control technology is the application of cybernetics technology. It is to complete a certain control task through an automatic control system with certain control function, ensure that a process is carried out as expected, or achieve a preset goal
automatic control technology:
1. Principle analysis:
from the perspective of control mode, automatic control system can be divided into closed-loop and open-loop
2. Closed loop control:

closed loop control is (negative) feedback control. The principle is similar to the purposeful behavior of humans and animals. The system consists of sensors (equivalent to senses), control devices (equivalent to brain and nerve), and actuators (equivalent to hands, legs and muscles). The sensor detects the state information (output) of the controlled object and converts it into a physical (Electrical) signal to the control device. The control device compares the deviation between the current state (output) of the controlled object and the desired state (given quantity), generates a control signal, and drives the controlled object to move through the actuator to make its motion state close to the desired state. In practice, there are many methods of closed-loop (feedback) control, which are applied in different fields and all aspects. At present, the widely used and rapidly developed ones are: optimal control, adaptive control, expert control (i.e. establishing control rules and procedures based on expert knowledge base), fuzzy control, fault-tolerant control, intelligent control and so on

3. Open loop control:

open loop control is also called program control, which sends signals to control objects in turn according to the predetermined program. According to the conditions of signal generation, open-loop control has time limit control, sequence control and condition control. Since the 1980s, programmable controllers produced by microelectronic technology have been widely used in industrial control (elevators, multi-step machine tools, waterworks). Of course, some complex systems or processes often use multiple control types and multiple types of control programs

4. Technology application:
with the development of computer technology and other high technologies, the level of automatic control technology is higher and higher, its application is more and more extensive, and its role is more and more important. It plays a key role in the fields of military engineering and automation, especially in the fields of Aerospace Engineering and automation.

basic information

automatic control technology is one of the fastest developing and most influential technologies in the 20th century and one of the most important high technologies in the 21st century. Today, technology, production, military, management, life and other fields are inseparable from automatic control technology. In terms of definition, automatic control technology is the application of cybernetics technology. It is to complete a certain control task through an automatic control system with certain control function, ensure that a process is carried out as expected, or achieve a preset goal

Principle analysis

from the perspective of control mode, the automatic control system has closed-loop and open-loop

Closed loop control

closed loop control is (negative) feedback control. The principle is similar to the purposeful behavior of humans and animals. The system consists of sensors (equivalent to senses), control devices (equivalent to brain and nerves), and actuators (equivalent to hands, legs and muscles). The sensor detects the state information (output) of the controlled object and sends it! Squid turns into a physical (Electrical) signal to the control device. The control device compares the deviation between the current state (output) of the controlled object and the desired state (given quantity), generates a control signal, and drives the controlled object to move through the actuator to make its motion state close to the desired state.

with the development of computer technology and other high technologies, the level of automatic control technology is higher and higher, its application is more and more extensive, and its role is more and more important. Especially in the fields of production process automation, factory automation, robotics, comprehensive management engineering, aerospace engineering, military technology and so on, automatic control technology plays a key role

automatic control technology, by definition, is the application of cybernetics technology. It is to complete a certain control task through an automatic control system with certain control function, ensure that a certain process is carried out as expected, or achieve a preset goal

automation technology is one of the most eye-catching high technologies with rapid development and wide application; It is the core technology to promote the new technological revolution and the new industrial revolution. Generally speaking, automation is to
use machines, equipment or systems to complete certain production tasks instead of people, or to realize certain processes instead of people, or to manage affairs instead of people. Strictly speaking, automation refers to the automatic realization of the expected operation or a certain process through automatic detection, information processing, analysis and judgment of machinery and equipment or production management process without the direct participation of anyone
automatic control system is a system that has certain functions and can complete certain control tasks. The composition and working principle of the automatic control system have many similarities with the composition and working mechanism of the human body: the automatic control system has sensors equivalent to human sensory organs, control devices equivalent to human brain and nervous system, and actuators equivalent to human hands, legs and muscles. The sensor is used to detect the command information, external change information and the state information of the controlled object, and transform it into an electrical signal to the control device. The control device calculates the difference between the current state of the controlled object (called the controlled quantity, or the output of the system) and the desired state (called the input signal), and generates the control signal according to a certain law according to this deviation (called the error signal), which is amplified and sent to the operation actuator. The operating actuator is used to drive the controlled object until its state reaches the desired state. The control formed by comparing the output of the system or other controlled variables of the system with the input of the system is called closed-loop control or feedback control.
