Adaptive Control Method for Cutting Path of Fuzzy PID Coal Mining Machine Based on Multi-Sensor Fusion
Adaptive control of cutting path is an important means to improve the production efficiency and quality of coal mining machines.However,the current method has low control accuracy.In practice,the RMSE and MAE of cutting path are relatively high.Aiming at the shortcomings and deficiencies of current methods,a fuzzy PID cutting path adaptive control method for coal mining machines based on multi-sensor fusion is proposed.Adopting multi-sensor fusion technology to perceive the position and status information in the cutting kinematic model of the coal mining machine,and fusing and processing the multi-sensor data,the cutting path of the coal mining machine is obtained based on the cutting kinematic laws of the coal mining machine.The cutting path deviation is fuzzified,and the PID controller is used to regulate the ratio,integral,and derivative parameters to correct the cutting path deviation of the coal mining machine,achieving adaptive control of the cutting path of the coal mining machine based on multi-sensor fusion using fuzzy PID.Experimental results have shown that the RMSE and MAE of the cutting path of the coal mining machine under the application of the design method have been significantly reduced,providing a certain reference for the adaptive control of the cutting path of the coal mining machine.
