The roll machine is used to roll the product, such as steel roll and toilet paper. The stable synchronism and the constant tension will decide the quality of the roll result. A novel control scheme is proposed in this paper for the control objective. Each feedback loop is controlled by the Grey-Fuzzy-Fuzzy controller. Two-layer fuzzy control is introduced to achieve precious synchronism and tension control. The Grey prediction is combined to overcome the problem of inertia. Finally, a prototype of roll machine is implemented for examining the proposed control scheme. Experimental results show that the Grey-Fuzzy-Fuzzy control is robust to against the external load. The experimental results also show that the proposed control rule has robustness and practical capability.
