Study of grouting pressure stabilization control system based on Fuzzy-PID control

To solve the self-control problem of grouting pressure stabilization in grouting engineering, a grouting pressure stabilization control system based on self-adjusting modifying factor Fuzzy-PID control was studied, its design idea is that when pressure deviation is larger, fuzzy control will be adopted to increase the response speed; when pressure deviation is smaller, the system will switch to PID control to eliminate static error and improve control precision. Simulation results showed that: the system was able to adapt to changes in object parameter, and behaved good control quality, high accuracy and fine stability, and achieved the desired targets.
