With the continuous enhancement of the level of modern industrial automation, conveyor belt is widely used in logistics, manufacturing and coal mining and other fields of key equipment, its consistency and control performance for production efficiency and safety are of great significance. PID control is the most extensive used control method at present. Its basic algorithm is simple and easy to understand, but it has some shortcomings in dealing with nonlinear and complex system control. Therefore, this study explores the performance of the conveyors dynamic control system controlled by fuzzy PID. In this study, MATLAB software is used to establish the corresponding simulation model, the control effect of conventional PID control, vague control and vague PID control three different control strategies are compared, and their advantages and disadvantages and application range are analyzed. The results show that the conveyors dynamic control system based on vague PID control has the best performance under various indexes, has better robustness and adaptive ability, and its control effect is better than the other two control strategies. Especially in the control of overshoot and rise time, vague PID control is significantly better than conventional PID control and vague control.
