  1. 1. Relay feedback and multivariable control

    University dissertation from Department of Automatic Control, Lund Institute of Technology (LTH)

    Author : Karl Henrik Johansson; Lunds universitet.; Lund University.; [1997]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; robotics; Automation; Frequency methods; Process control; Sequential control; Automatic tuning; Control education; Laboratory process; Performance limitations; Decentralized control; Multivariable zero; Multivariable systems; Hybrid control; Nonlinear dynamics; Limit cycles; Oscillations; Relay feedback; Sliding modes; control engineering; Automatiska system; robotteknik; reglerteknik;

    Abstract : Popular Abstract in Swedish Återkoppling är en fundamental princip inom reglertekniken. Genom att mäta vissa variabler kan andra påverkas så att ett system uppför sig på önskat vis. Denna doktorsavhandling behandlar två typer av återkoppling: reläåterkoppling och flervariabel återkoppling. READ MORE

    Abstract : The need for improved energy usage has become a key issue in all industrial sectors. In the energy demanding production of mechanical pulps many efforts have focused on design development, but regarding control of refiners, there is still a potential for improvements. READ MORE

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

    University dissertation from Department of Automatic Control, Lund Institute of Technology, Lund University

    Author : Ola Slätteke; Lunds universitet.; Lund University.; [2006]
    Keywords : 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;

    Abstract : 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. READ MORE

  5. 5. Perturbation-based Control of Industrial Fed-batch Bioprocesses

    University dissertation from Department of Automatic Control, Lund Institute of Technology, Lund University

    Author : Ola Johnsson; Lunds universitet.; Lund University.; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; perturbation-based control; process control; fed-batch control; industrial bioprocesses;

    Abstract : The topic of this thesis is bioprocess control, more specifically control of industrial-scale microbial fed-batch bioprocesses. Its focus is therefore on methods which are easy to implement in an industrial setting, which gives certain limitations on sensors, actuators and control systems. READ MORE
