Abstract

Paper machines are very complex processes. Identification models, sometimes, cannot meet operational requirements. It is very difficult to develop paper machine dynamic models solely by theoretical mechanism analysis. In this chapter, a systematic modeling method for paper machines is proposed, which combines mechanism analysis with experimental method. The model structure and part of model parameters are determined from mechanism analysis. The remaining model parameters are obtained from experimental data. The modeling process for a pressurized headbox and a paper machine which produces condenser tissue (with an open headbox) is presented.
