A novel method for mixture viscosity control based on change detection

Svantesson, T and Olsson, Gustaf LU (2004) In Control Engineering Practice 12(1). p.11-22
Abstract
The paper presents a novel method for detecting abrupt changes in mixture viscosities. This problem arises in numerous industrial applications and different solutions are suggested in the literature. An approach of using non-linear filtering for detection-an adaptive filter combined with a change detector-is outlined in this paper. As a case study, we present an ash stabilization batch mixing process used to stabilize a blend of ash/dolomite/water. The main problem is here to predict the quantity of water to be added, since the required amount of water varies with the wood ash quality. One adaptive filter and two change detectors are applied to benchmark data and the detectors are evaluated using basic performance measures. (C) 2002... (More)
