Composition of automated control system

The automated control system is a system that can automatically adjust and control process variables to achieve predetermined goals. The system consists of the following main components:

1. Sensors and measuring equipment

• Detect and measure controlled parameters (such as temperature, pressure, flow) and Convert them into electrical signals.

2. The controller

• receives the signal from the sensor, calculates the required control action according to the predetermined algorithm, and issues instructions to the actuator .

3. The actuator

• executes the instructions of the controller and changes the value of the controlled parameter (such as opening or closing the valve, starting or stopping motor).

4. Feedback loop

• feeds back the current value of the controlled parameter to the controller so that the controller can adjust according to the deviation.

5. Human Machine Interface (HMI)

• Allows operators to interact with the system, view process data and modify control parameters.

6. Communication Network

• Connects different components in a system, allowing signal transmission and data sharing.

7. Software

• executes control algorithms, human-machine interface functions and communication protocols.

8. Power and Wiring

• Provides power to system components and ensures reliable connections.
