Popis:	Generalized predictive control, GPC , has been implemented in two ferrosilicon furnaces at Icelandic Alloys Ltd for controlling the silicon ratio in tapped metal. The control is based on an ARX model of the furnace. The model is used to predict the silicon ratio one and two time steps ahead. The use of GPC has resulted in decreased variations in the chemical analysis of tapped metal, and better results are also achieved in terms of keeping the silicon ratio near the desired value.
