An application of qualitative modelling in an intelligent process supervisory system

Abstract

This paper describes the progress that has been made in this area. The ideas of qualitative systems theory are extended to qualitative transfer function (QTF) models, and are then used to analyse the properties of a detailed QTF model of a distillation process. It is shown that these analytical tools can prove extremely useful in developing such models. Results from examples showing how the qualitative model can be used in an intelligent supervisory system are also presented.<>
