    Sammanfattning : New combustion engine principles increase the demands on feedback combustion control, at the same time economical considerations currently enforce the usage of low-end control hardware limiting implementation possibilities. Significant development is simultaneously and continuously carried out within the field of Field Programmable Gate Arrays (FPGAs). LÄS MER

  2. 2. Modeling and Control of the Paper Machine Drying Section

    Detta är en avhandling från Department of Automatic Control, Lund Institute of Technology, Lund University

    Författare :Ola Slätteke; Lund University.; Lunds universitet.; [2006]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; reglerteknik; robotteknik; Automatiska system; Moisture control; Paper-making; Pressure control; Predictive Control; Mid-ranging Control; Wood; Drying Section Modeling; Automation; control engineering; robotics; pulp and paper technology; Pappers- och massateknik;

    Sammanfattning : The topic of this thesis is modeling and control of the last part of the paper machine - the drying section. Paper is dried by letting it pass through a series of steam heated cylinders and the evaporation is thus powered by the latent heat of vaporization of the steam. LÄS MER
