Research on Intelligent Cutting of Shearer based on BP-PID Control

To achieve intelligent coal cutting with a shearer and reduce production losses, this study conducted simulation research on the speed regulation and height adjustment performance of the shearer under different control strategies. A BP-PID-based intelligent cutting scheme was proposed, and a comparative analysis of traction speed control and height adjustment strategies was carried out. The study found that, in terms of speed regulation, compared with fuzzy PID control, the BP-PID-based scheme exhibited faster response and higher control accuracy. In terms of height adjustment, compared with conventional PID and fuzzy PID control, the BP-PID-based method demonstrated the best trajectory tracking performance with smaller tracking errors and better adaptability to complex changes in the cutting path. These results provide a useful reference for achieving intelligent and efficient coal mining.
