Abstract：To address the issues of high cost,complex equipment,and difficulty in ensuring and pre-cisely controlling the flow ratio accuracy of traditional dual-fluid grouting pumps,a dual-fluid grouting pump ratio adjustment system based on PID control(proportional-integral-differential con-trol)is proposed.The system achieves precise control of the grouting ratio of the dual-fluid grouting pump by setting the proportional coefficients of the flow rates of grouting pump A and grouting pump B,using two flow feedback signals and two PID closed-loop controls.It simplifies the equipment and reduces the cost.A simulation model was established using Matlab to conduct dynamic performance simulation and experimental verification of the system scheme.The dynamic variation laws of the sys-tem under different parameter changes were analyzed.The results show that this algorithm has stabil-ity and reliability when the grouting system is disturbed.
