Fuzzy Prediction Control for Coiling Temperature of Hot Tandem Rolled Strip

In accordance with features of dead time in strip temperature control system of laminar cooling in hot strip mill, Fuzzy prediction control method is introduced. The regulation time and response time of the newly developed controller are shorter than those of traditional one. The instability caused by pure lagging effect can be eliminated effectively. This control method has been applied in a hot strip mill owing to its easy realization and high stability. The accuracy of coiling temperature can be controlled within ±10 ℃.
