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忆s dynamic property and strengthen its anti-interference.
