What is an automatic control system?

　　For example, quenching oil tank automatic control system includes unified control of heating system, cooling system, lifting system, mixing system, fire extinguishing system, safety system and other systems to realize automatic production.
　　The following is a clear concept of the system. A system is a combination of several components that combine to accomplish a certain task. It should be noted that the system is not limited to physical systems, but can also be applied to abstract dynamic phenomena. The automatic control system refers to a system that can automatically control the working state of the controlled object.
　　The automatic control system is generally composed of a control device and a controlled object. The controlled object (referred to as the controlled object) refers to the machine, equipment or production process that requires automatic control, such as artificial earth satellites, aircraft, machine tools and chemical production processes. The control device refers to the overall equipment that controls the controlled object, including measuring devices, comparison devices, amplification devices, and actuators.
　　The composition and functions of the automatic control system are diverse. It can be a simple system that only controls a physical quantity (such as temperature, pressure, voltage, etc.), or it can include an enterprise., The complex system of the entire process of the organization; it can be a specific engineering system, it can also be an abstract social system, ecological system or economic system.
