Speed Control of an Experimental Hot-rolling Mill Using Generalised Predictive Control
نویسندگان
چکیده
The application of Generalised Predictive Control (GPC) for an experimental hot-rolling mill is presented in this paper. GPC has been implemented to provide the mill with good speed control and regulation when steel and aluminium hot-rolling experiments are carried out. Using an identification mechanism, GPC first estimates the mill’s model and predict the future behaviour of the rolling speed to finally calculate a sequence of future control actions. The performance of GPC was evaluated via simulations and realtime experiments under different operating conditions. From such experiments it can be concluded that the proposed control scheme performs reasonably well, showing good robustness and disturbance rejection in all operating modes. Copyright © 2006 IFAC

Investigations into the Effect of Tension Between the Stands of the Finishing Mill on Width Control in a Hot Rolling Process
This paper is concerned with investigations into the effect of tension between the stands of the finishing mill on width control in a hot rolling process. An analysis is given to predict satisfactorily the variation in width due to spreading and also due to strip tension between the stands. Wusatowski's model which is developed to give an account of spreading is specified and a similar model to...

متن کاملPrediction of Work-Piece Constitutive Equation in Hot Rolling of Strip
Dimensional control of the work-piece in steel industry is of important interest. The main aspects in overcoming the thickness control are variations in material strength due to variations in chemical composition, work-piece temperature, reduction and the strain rate applied to the work-piece. In this paper based on the main parameters affecting the rolling force an attempt been made to give a ...

متن کاملFeedforward control of lateral asymmetries in heavy-plate hot rolling using vision-based position estimation
This paper presents a feedforward control concept for lateral asymmetries in heavyplate hot rolling. A lateral off-center plate position generally entails asymmetric rolling forces, asymmetric mill stretch, and thus a wedge-shaped exit thickness that may cause a cambered plate contour and a rotatory motion of the plate. In this paper, a model of the mill stand and of the plate movement is prese...
