摘　　要：基于掘进机截割作业过程中截割岩壁的随机性造成负载变化幅度较大的问题,建立自适应模糊控制的掘进机截割电机恒功率调速控制系统,可以实现依据监测电流值与设定电流偏差情况进行模糊推理,对输出电流进行自适应调节控制,实现截割电机的恒功率控制。通过仿真试验发现,该调速方式调节效果较好,极大提高了掘进机截割系统的稳定性。Based on the current situation that the randomness of cutting rock wall during the cutting operation of roadheading machine causes a large change of load,a constant power control system of cutting motor of roadheading machine with adaptive fuzzy control is established to realize constant power control of cutting motor by fuzzy reasoning based on the deviation of monitored current value and set current and adaptive adjustment control of output current.Through the simulation test,it is found that the regulation effect is good and the stability of the cutting system of the roadheader is greatly improved.
