Research and Application of Adaptive Control of Scraper Conveyor in Coal Mine Comprehensive Digging Face
Aiming at the low degree of automation control of scraper conveyor and poor straightness accuracy faced by a mine at present,a straightness control method of scraper conveyor based on fuzzy adaptive PID control is proposed,the causes of error are analysed in-depth,the fuzzy adaptive PID controller is designed for the purpose,and the performance of straightness control method of scraper conveyor is simulated and verified by Matlab software,and finally industrial verification is carried out at the actual working face.Simulation verification,industrial verification in the actual working face,the final results show that:the designed scraper conveyor straightness control method to complete the position prediction and adjustment of the central groove,and its overall straightness to maintain the enhancement of nearly 15％,and reflect the position error in the range of±1.2 cm for the intelligent reform of the working face equipment to provide reference.
