The Herrenknecht shield machine air automatic aeration system is used to keep the air pressure in the soil bin close to a constant value. It is a pressure automatic control system. In order for the control system to achieve the expected control effect, the PI (proportional integral) regulator parameters that affect the dynamic performance of the system must be correctly set. At the same time, the shield machine works in a harsh environment. The spring fatigue and diaphragm aging of the aeration system will cause the regulator parameters to change, resulting in system control failure. Therefore, the regulator parameters must be adjusted frequently during use.
