In this paper, conditions of the chaos in auto gauge control system are suggested and proved on the basis of the roll eccentricity model.It is proposed that the eccentricity disturbance of roll may cause chaotic phenomena in the rolling process.By analyzing four kinds of expandable and shrinkable factors of variable universe fuzzy controller, it is suggested that the contradiction between fuzzy control rules and control accuracy can be solved effectively by HACO-VUFC method.Simulation shows that the product quality can be improved by chaos inhibition.
