摘　　要：针对现有采煤机调高控制系统存在的流量控制不精确、动作滞后性大、实际调高与要求调高差距大的缺点,提出了一种新的自动调高控制系统。该系统实现了对采煤机滚筒调高的精确控制和稳定微调,降低了系统调整的工作时间,提高了系统性能和响应速度。In this paper, a new automatic height control system is put forward in view of the shortcomings of the existing height control system of the shearer, including imprecise flow control, large lag in action and wide gap between actual and required height adjustment. The system realizes accurate control and stable fine adjustment of the height of the shearer drum, and reduces the working time of the system adjustment. Improve system performance and response speed.
