During underground excavation, there is significant disturbance and the intelligence of temporary support is imbalanced, resulting in the inability of self moving temporary support to effectively control the roof based on the changes in surrounding rock generated during the mining of comprehensive excavation tunnels, which seriously affects the personal safety of underground workers. In response to the phenomenon of poor adaptability between temporary support and roof during tunnel excavation, an adaptive temporary support based on fuzzy PID control is introduced. The adaptive hydraulic control system of the support is analyzed, and the target function of fuzzy PID control is obtained by combining the three major equations of the hydraulic system. Using Simulink to establish an adaptive control system model, a MATLAB simulation platform was used to simulate the system using traditional PID control methods and fuzzy adaptive PID control. The temporary support adaptive control system was simulated and studied. After simulation experiments, it was shown that using a fuzzy adaptive PID controller system can make up for the shortcomings of conventional PID controllers. Compared with traditional PID control, fuzzy PID control is used, The adaptive control system for the support needs about 0.12 seconds to stabilize, which is reduced by 23 times, and is well adapted to the surrounding rock pressure of the roof. This proves that fuzzy PID control can effectively achieve adaptive effects on the temporary support and its pressure tracking effect is better than traditional PID control.
