Expert control of vacuum pan crystallisation

Vacuum pan crystallisation is a process which is very difficult to control by classical means. This paper presents a method for using a rule-based expert system for the control of such a process. The structure of the expert controller for adjusting the characteristic conductivity is shown. It consists of a diagnostic expert system and a discrete dynamic model which is used for conversion of semantic results into numeric output values. The expert controller will be practically implemented in the sugar factory in Lovosice.<
