Design of Automatic Tracking System for Cutting Trajectory of Coal Mining Machine
In order to solve the problems of low efficiency and poor safety of coal mining machine relying on manual control,on the basis of the analysis of the principle of automatic height adjustment of coal mining machine trajectory tracking,the sampling period and knife feeding method of the automatic tracking system of cutting trajectory are determined;a scheme based on multi-sensor monitoring of the cutting status of coal mining machine is proposed,and an automatic tracking control module is designed for it.Finally,the control effect based on speed feed-forward fuzzy PID control strategy is verified.
