Research on Intelligent Feeding Paper Control System Based on Fuzzy Parameter Self-Adaptive PID for Fruit-Bag Machine

This paper presents a control system of feeding paper in fruit-bag machine based on fuzzy parameter self-adaptive PID. First, it put forward the mathematical model of control system according to the design characters. Then, it analyzed the structure and rules of controller and estimated the fuzzy parameters of PID by evaluating fuzzy relations equation. By the theoretical analysis and system¿s experimental test show that fruit-bag machine can automatically adjust deviator location according to roll size while feeding paper. It could solve the problem of paper wrinkling caused by drifting or deviation, incorrect congruence of internal and external bag. It apparently strengthens the stability of the whole producing process and improved the quality of fruit-bag.
