摘要
为解决采煤机无法根据煤岩条件对其截割高度进行自主、高精度控制的问题,以MG300/711-WD采煤机为研究对象,在对其调高系统液压分系统进行改进的基础上,提出了基于煤岩识别的高精度轨迹跟踪控制系统,并为其配套基于速度前馈的PID控制策略,降低了采煤机截割岩层的风险.
Abstract
In order to solve the problem that coal mining machine cannot control its cutting height autonomously and with high precision according to coal and rock conditions,taking MG300/711-WD coal mining machine as an example,based on the improvement of hydraulic sub-system of its height-adjusting system,a high-precision trajectory tracking control system based on the identification of coal and rock has been proposed,and it is equipped with the PID control strategy based on the feed-forward of the speed,which reduces the risk of the rock cut of the coal mining machine.The risk of coal mining machine cutting rock layer is reduced.
