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 they can be automatically adjusted and returned to the process when they are deviated from the normal state due to external interference (disturbance) Within the required numerical range. Various technological conditions cannot be static in the production process. Especially for chemical production, most of them are continuous production, and each equipment is interrelated. When the process conditions of one of the equipment change, it may cause some parameters in other equipment to fluctuate more or less, deviating from the normal process. condition.
