Abstract

Application of the data driven modelling framework entitled Grid of Linear Models to derivea predictive model for a fed-batch fermentation process is presented. The modelling framework utilises a large numberof local linear models to approximate the behaviour of the non-linear process.Industrial data from a fed-batch fermentation has been supplied by Novozymes A/S.A model for the process has been identified based on these data.The model possesses good predictive capabilities and it is intended to be implemented in a model predictive control framework.
