Abstract: Aiming at the problem of uneven speed of the double motor of the screw pile machine, the structure and working characteristics of the pile drilling control system were studied. The control strategy of the drilling system based on fuzzy control theory was summarized. System parameters were reasonably set .The simulation of the screw pile motor was carried out by Simulink, and the characteristic curve of the double motor speed was obtained.Field test was carried out on the screw pile machine drilling control system with fuzzy controller, and the speed of the power head double motor was tested.The results indicate that the maximum speed difference of the two motors based on fuzzy control strategy is significantly reduced, which significantly improves the problem of uneven speed of the dual motor of the power head. The field test results verify the correctness of the fuzzy control strategy. This study provides theoretical technical support and effective practical guidance for the design of drilling control scheme for screw pile machine.
