Fuzzy Supervisory Systems for Bioprocess Diagnosis and Control

摘要

It has been shown during recent years that artificial intelligence (AI)technologies can be successfully employed in the area of bioprocess modelling and control. The aim of this work was to build easy-to-use intelligent systems to support the operator, and aid in bioprocess diagnosis and control by acting as supervisory control systems to support the operator, and aid in bioprocess diagnosis and control by acting as supervisory control systems and by utilizing heuristic expert knowledge about the process. For that purpose, an object-oriented programming environment, Smalltalk/V Mac, was employed in a Macintosh computer. In the system developed, fuzzy logic was utilized to handle uncertainties in process knowledge and measurements. Example applications during the system development were provided by lactic acid fermentation and fed-batch baker's yeast cultivation.
