摘　　要：采煤机在综采作业中所受到的载荷具有随机性,应用模糊自适应PID控制策略,针对采煤机调高机构的几何非线性特点和采煤机作业中单向信息的采集偏差现象,对采煤机双向截割滚筒高度进行自动跟踪,并给出了单向示范刀顶板和底板的数字化模型,通过对单向示范刀记忆截割曲线跟踪控制的模拟仿真,得到误差曲线,为采煤机单向示范刀记忆调高系统的设计优化提供理论支持。The load of shearer is random in a fully mechanized operation, aiming at the geometrical non-linearity of the higher institutions and the deviation phenomenon of one-way information acquisition of coal winning machine, the paper applied the fuzzy adaptive PID control strategy to automatic track the height of the two-way cutting drum of shearer, and presents digital model of roof and floor of single demonstration cutter. At last, gets the error curve by simulating the track and control of the single demonstration cutter, provides the theoretical support to the design optimization of single demonstration cutter system memory.
