PID control, namely proportional integral derivative control, is one of the earliest control strategies developed. Because of its simple algorithm, good robustness and high reliability, it is widely used in industrial process control. So far, about 90% of control loops have PID structure.

PLC control system is a new generation of industrial control device formed by introducing microelectronic technology, computer technology, automatic control technology and communication technology on the basis of traditional sequence controller.

Zhengwei reactor is equipped with PID or PLC controller according to customer needs, which can realize the full automation of stirring speed, heating temperature, feeding and discharging, and material handling.
