Constant pressure water-supplying system based on fuzzy PID for dust-reducing spray at fully mechanized coalface

This paper proposes a strategy of fuzzy PID control for constant pressure water-supplying system to reduce the dust by spray at fully mechanized coalface. Simulation analysis of the system was carried out under different working conditions using SIMULINK software. The simulation results show that the time for the system to reach a stable value using fuzzy PID control was 5 s shorter than that using fuzzy PID control, and the speed for the system to restore stability after disturbance was 36% higher than that using PID control, and the former had no major overshoot phenomenon. The proposed strategy improved the static and dynamic performance of the system, thus met the requirement of constant pressure water-supplying system for dust-reducing spray at fully mechanized coalface, demonstrating its feasibility.
