Design and Simulation Analysis of High-Precision Trajectory Tracking Control System for Coal Mining Machine
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.
