Paper machine modeling at Norske Skog Saugbrugs: A mechanistic approach
In this paper a mechanistic model of a paper machine is presented. The model is developed as a foundation for the control of three selected variables; the basis weight, the paper ash content, and the white water total concentration (or wire tray total concentration). The model is of high order and reduced order models are developed and fitted to experimental and operational mill data. The fitted models are validated with historical operational data.
