Abstract：

Deviation of the center line for rolled piece from the center line of rolling mill is easily generated in rolling process because of transverse unsymmetrical factors of rolling. It loads to the problems of aluminum strip snap, winding misalignment, and so on. For the deviation phenomenon, the fuzzy control method was used to control the deviation process based on deviation mathematic model. Using the deviation value and its change rate as the input, the roll gap difference as the adjustment, the fuzzy rule was built by experience method, and the fuzzy control model was built based on MATLAB software. Furthermore, the simulation based on rolling operating data on the industrial scene was conducted to validate the accuracy of this deviation control model.
