摘要
针对螺杆桩机动力头双电机转速不均的问题,对桩机钻进控制系统的结构和工作特点进行了研究,对基于模糊控制理论的钻进系统控制策略进行了归纳。提出了一种基于模糊控制的双电机模型,设置了合理的系统参数,利用Simulink对螺杆桩机电机进行了仿真分析,获得了双电机转速的特性曲线;对采用了模糊控制器的螺杆桩机钻进控制系统进行了实地试验,并测试了动力头双电机的转速。研究结果表明:基于模糊控制策略的双电机最大转速差明显减小,显著改善了动力头双电机转速不均的问题;实地测试结果验证了提出的模糊控制策略的正确性;该研究为螺杆桩机钻进控制方案的设计提供了理论技术支持和有效实践指导。
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.
