Complete Partial Control Design for Extractive Fermentation Process

In this paper, the methodology for complete partial control design based on a novel PCA-based technique incorporating the inventory and constraint control objectives is described. Brief descriptions on the PCA-based technique, some definitions and criteria are also presented. The application of the methodology is demonstrated using a case study of extractive alcoholic fermentation process. Result shows that good understanding of the interaction among process variables is the key principle for designing partial control strategy. Interestingly the proposed methodology allows the designer to understand this interaction and hence to exploit its benefit in partial control design.
