Abstract
This paper describes how a self-tuning feedforward-feedback control strategy could be implemented on a three-zone forehearth as used in the manufacture of glass containers. Experimental results, based upon real operating data, are presented in order to evaluate the control algorithm. It is shown how an existing model of a forehearth zone can be modified by the introduction of a self-tuning parameter, which enables the model to predict the glass surface temperature from the exit of any forehearth zone. The proposed control strategy for one zone of the forehearth is then modified to incorporate the self-tuning parameter, which makes it suitable for controlling each zone of the forehearth. Simulation results, using real operating data records, clearly show the effectiveness of the self-tuning parameter for the model as well as the control stategy.Keywords
