Automatic control system

Automatic control system refers to the use of some automatic control devices to automatically control certain key parameters in production, so that when they deviate from the normal state due to external interference (disturbance), they can be automatically adjusted and returned to the numerical range required by the process. The various process conditions in the production process cannot be static. Especially in chemical production, most of them are continuous production, and various equipment are interrelated. When the process conditions of one equipment change, it may cause some parameters in other equipment to fluctuate more or less, deviating from normal process conditions. Of course, automatic adjustment refers to the absence of direct human involvement.
