  1. 1. Grey-box Identification of Distributed Parameter Systems

    Författare :Yi Liu; Elling W. Jacobsen; Denis Dochain; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical engineering; grey-box modeling; grey-box identification; model reduction; PDE; chromatography; bifurcation; moving mesh methods; orthogonal collocation on moving finite elements; OCMFE; Elektroteknik; elektronik och fotonik; Electrical engineering; electronics and photonics; Elektroteknik; elektronik och fotonik;

    Sammanfattning : This thesis considers the problem of making dynamic models for industrial processes by combining physical modelling with experimental data. The focus is on distributed parameter systems, that is, systems for which the model structure involves partial differential equations (PDE). Distributed parameter systems are important in many applications, e. LÄS MER

    Sammanfattning : The contents of this thesis can be divided into two main parts. The first one is the development of an identification methodology for the modelling of complex industrial processes. The second one is the application of this methodology to the curl and twist problem. LÄS MER

  5. 4. On Modelling and Estimation of Curl and Twist in Multi-Ply Paperboard

    Författare :Gianantonio Bortolin; KTH; []
    Nyckelord :modelling; grey box; curl;

    Sammanfattning : This thesis describes a grey-box model for the dimensionalstability properties (i.e. curl and twist) of the carton boardproduced at AssiDomän Frövi paper mill in Sweden.AssiDomän Frövi AB is one of Sweden major cartonboard manufacturer, and produces some 350000 ton of board peryear.

  7. 5. Modelling the Moisture Content of Multi-Ply Paperboard in the Paper Machine Drying Section

    Författare :Christelle Gaillemard; Anders Lindquist; ALf Isaksson; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Drying section modelling; multi-ply paperboard; moisture content; identification; grey-box modelling; Optimization; systems theory; Optimeringslära; systemteori;

    Sammanfattning : This thesis presents a grey-box model of the temperature and moisture content for each layer of the multi-ply paperboard inside the drying section of a paper mill. The distribution of the moisture inside the board is an important variable for the board quality, but is unfortunately not measured on-line. LÄS MER
