Taking the scraper conveyor for coal mine as the research object,the tension control system is designed by considering the influence of impact load on tension when the equipment is running.The core of the system is fuzzy PID control technology,which gives full play to the advantages of fuzzy control and PID control technology and guarantees the control reliability and precision of the system.Through simulation,it is found that the fuzzy PID control technology has higher control accuracy,and its response time is about 2 s,which can meet the requirements of actual use in coal mines.Deploying the system into coal mine engineering practice,through one year's practical application,it was found that the equipment did not have any fault problems of chain skipping and chain stacking,creating good safety benefits and economic benefits.
