Abstract ：Industrial automation level has become a measure of professions modernization level is an important symbol. At the same time, the development of the theory of control also experienced the classical control theory and modern control theory and intelligent control theory of three phase automatic control system can be divided into the open loop control system and closed-loop control system. A control system including the controller, sensors, actuators, and transmitter input and output interface. The output after output interface, actuators, add to the control system, Control system, the accused, the transmitter, through after sensor input interface to controller. Different control system, its sensors and actuators, the transmitter is not the same. At present, the PID control and controller or intelligent instrument has many PID controller in the engineering practice, the products have been widely applied, there are all sorts of PID controller products, companies are developed with PID parameter self-setting function of intelligent regulator (intelligent regulator), including the PID controller is adjusted by intelligent automatic adjustment or calibration, the adaptive algorithm is proposed to realize. Have realized using PID control pressure, temperature, flow, liquid level controller, can realize PID control function of the programmable logic controller (PLC), and can realize PID control PC system, etc.

Key words: intelligent control, PID control
