Atomatic control system refers to the use of some automatic control devices to automatically control some key parameters in production, so that when they deviate from the normal state under the influence of external interference (disturbance), they can be automatically adjusted to return to the value range required by the process. Various process conditions in the production process cannot be unchanged, especially in chemical production, most of which are continuous production, and various equipment are interrelated. When the process conditions of one equipment change, some parameters of other equipment may fluctuate more or less, deviating from the normal process conditions. Of course, automatic regulation means that no direct human participation is required. The automatic control system is composed of a controller and a controlled object. However, in order to realize complex control tasks, a typical automatic control system should generally include: fixed value element, executive element, measurement and transmission element and comparison element. According to different control principles, the automatic control system is divided into open-loop control system and closed-loop control system. Open loop control system: in the open loop control system, the system output is only controlled by the input, and the control accuracy and interference suppression characteristics are poor. In the open-loop control system, the logic control based on time sequence is called sequential control system; It is composed of sequence control device, detection element, actuator and controlled industrial object. It is mainly used in the control of machinery, chemical industry, material handling and transportation, as well as the manipulator and automatic production line. Closed loop control system: the closed loop control system is based on the feedback principle. It controls the system by using the deviation of the output and the expected value, and can obtain better control performance. Closed loop control system is also called feedback control system. According to the given signal classification, the automatic control system can be divided into constant value control system, follow-up control system and program control system.BENEFITS:(I WILL GIVE YOU A REPLY IMMEDIATELY)
