摘　　要：针对采煤机记忆程控滚筒调高的特征,对不等作用面积的液压缸,提出了一种新的模型处理方法,考虑采煤机姿态和牵引速度等的影响,系统采用密采稀存的方式,实现滚筒位置高度的记忆再现控制.对某一调高液压控制系统的模型,给出其原理仿真图,应用Matlab语言Simulink软件包进行相应的数字仿真,为系统设计和动态特性分析奠定了基础.Based on properties of the memory programmed hydraulic control system for height adjustment of shearer＇s drum, a novel model of unequal action areas in a hydraulic pressure cylinder is established. With regard to the shearer＇s patterns and traction speeds, a mode called ＇dense excavation and sparse storage＇ is applied. Accordingly, the height of drum＇s positions is used for memory recovery control. Furthermore, the mechanism simulation diagrams of hydraulic control system are attained. In this manner, the digital simulation is conducted using Matlab Simulink^TM, Therefore, this approach paves a new venue for system design and dynamic property analysis.
