Application of Fuzzy-PID Control in Crosscut Feeding Speed Control of the Composite Paperboard

Objective To accurately control the feeding speed of the Cross- Cut machine during the manufacturing process of the high- strength paper board,which will help to improve its integral strength and production efficiency,the method of controlling the motor speed was studied. Methods Firstly,the manufacturing flow of the high- strength composite paper board was introduced,and a hardware system focused on the speed control of the Cross- Cut machine was designed. A nested control method with PID and fuzzy control was adopted for designing the fuzzy- PID speed control system,which was capable of self-tuning its parameters,and the system was simulated. Results The overshoot of the Fuzzy- PID control system was less than 5%,the adjusting time was reduced by more than 30% in comparison with the traditional PID control method,and the oscillation was almost excited at the late stage. Conclusion This nested fuzzy- PID control has the advantage of low overshoot and fast response,which improves the system's dynamic property and strengthen its anti- interference.
