Researchers: Per-Olof Gutman, Anders Lindquist, Xiaoming Hu, Gianantonio Bortolin in cooperation with with Bengt Nilsson (AssiDomän Carton Board AB, Frövi), Johan Tryding (AssiDomän Corporate R&D, Skärblacka), Hilding Elmqvist (Dynasim AB, Lund), and Pontus Ryd (Solvina AB, Göteborg).
Sponsors: The Swedish National Board for Industrial and Technical Development (NUTEK) through its KTS (Complex Technical Systems) program, and AssiDomän Carton Board AB, AssiDomän Corporate R&D, Dynasim AB, and Solvina AB.
The project started in April 1999. The aim of the project is to integrate existing models of the paper board manufacturing process at AssiDomän Carton Board AB, together with on-line identification routines, into a comprehensive Modelica model with the purpose of interactive operator simulation and operator assisted optimization of important quality variables.
Dynamic models will be developed for those subprocesses for which suitable models do not exist. A library of reusable model components will be developed in the new modeling language Modelica.
The following has been achieved during 1999/2000: A Modelica model for the wet end of the AssiDomän Carton Board AB carton board machine KM5 in Frövi has been written, as well as a preliminary model for the drying section. Modelica language elements for the purpose of the project have been developed. Gianantonio Bortolin has been recruited as a graduate student and will write an licentiate thesis on one of the modelling topics.
The project can be seen as a continuation of the project ''Robust quality control for paper manufacturing'' that was completed last year.
