Reconciliation of Measurement Data in Fermentation Using On-line Expert System

Abstract

A real-time expert system is being developed using 0PS83 rule based programming system for monitoring and analysis, diagnosis of faults and malfunctions, and on-line optimization of fermentation processes. The main purpose of the expert system is to assist the operators in running and improving fermentation conditions with minimum amount of supervision. The expert system consists of a data base which includes physical attributes of the process (color, and general appearance of the fermentation broth) and includes operator/user given off-line data like microscopic states of the microorganisms. Optimization and estimation algorithms can be interfaced with the expert system. These can be used in conjunction with the fault detection capabilities of the expert system for making intelligent decisions about the abnormalities in fermentation experiments, and rule out contradictory sensor information.
