Application of Advanced Control Methods in the Pulp and Paper Industry

Summary Digital computers have been used for process control in the pulp and paper industry for more than twenty years. This paper reviews the applications of advanced control methods to pulp and paper unit process control reported during the last decade. Modern control theory and adaptive control theory are most often applied to paper machine and headboxes. However a large number or reports deal only with simulated or laboratory scale processes. Indeed very few industrial applications are reported. Some of the reasons for this are analyzed and future trends briefly discussed.
