Aiming at the problems of slow response speed, poor regulation, time-varying and nonlinear tensioning control of traditional belt conveyor tensioning system in mine, a Fuzzy-PID control (PID control based on fuzzy algorithm) method of hydraulic tensioning system of belt conveyor in mine is proposed. Firstly, a mathematical model is established according to the hydraulic tensioning device, and secondly, the hydraulic tensioning system with Fuzzy-PID controller and PID controller are simulated by the built-in Simulink simulation library of Matlab, respectively, to derive the start-up response stage of the conveyor belt tensioning force and the regulation response graph of the sudden change of tension, and to make a comparative analysis. Finally, the effectiveness of the algorithm model is verified by experimental tests. The simulation results show that the hydraulic belt conveyor tensioning Fuzzy-PID control system has better steady state performance and faster response speed not only in the start-up phase but also during the sudden change of tension. The overshoot of tension in the start-up response phase of the tensioning device is reduced by 13.5%, and the time to reach the desired value is shortened by 0.5 s. The tension change of the tensioning device is the simulated tensioning and loosening stage, when the tension is increased, the speed of regulation of the Fuzzy-PID controller is shortened by 0.4 s, and the overshoot is reduced by 4%. When the tension decreases, the regulation speed of the Fuzzy-PID controller is shortened by 0.3 s and the overshoot is reduced by 2%. The experimental results show that the effect of using Fuzzy-PID control is better and more stable with less loss. Compared with PID control, Fuzzy-PID control is more effective, the average time is reduced by 31% and the overall tendency is stable. For the mine belt conveyor such as continuous transportation equipment, Fuzzy-PID control technology for the mine belt conveyor smooth operation provides a certain guarantee, not only reduces the waste of electricity, but also reduces the maintenance cost of maintenance belt conveyor.
