Study on Adaptive Fuzzy-PID Grouting Pressure Stabilization Control System
To solve the self-control problem of grouting pressure stabilization in grouting engineering, a grouting pressure stabilization control system based on adaptive Fuzzy-PID control was studied. Grouting pressure was dynamically measured and controlled by this system with sensor technology, microcomputer technology and control technology, the interface between the sensor and the host computer was designed. Based on 80C196 chip microcomputer，KP，KI and KD of PID control are automatically adjusted by fuzzy control rule，and electric control valve was controlled to keep grouting pressure precise and stable by adaptive Fuzzy-PID Control. Simulation experiments results show that: the system is able to adapt to changes of object parameter, and achieves the desired targets with good control quality, high accuracy and fine stability.
