  1. 16. Digital reglering av klimatprocesser

    Författare :Lars Jensen; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Uppvärmning; Ventilation; Reglerteknik; Datorstyrning; Digital teknik; Air conditioning; Mathematical models; Experimentation; Temperature control; Humidity control; Computer simulations; uppvärmning; ventilation; reglerteknik; digital teknik; datorstyrning;

    Sammanfattning : Results from a research project supported by the Swedish Council for Building Research are reported. The main task was to improve climate control technology. The work was focused on digital control. It was split up into three main tasks: model building, design of regulators, and fullscale experiments. LÄS MER

  3. 17. Predictive Control of HCCI Engines Using Physical Models

    Författare :Anders Widd; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Model Predictive Control; HCCI engine; engine control;

    Sammanfattning : Homogeneous Charge Compression Ignition (HCCI) is a promising internal combustion engine concept. It holds promise of combining low emission levels with high efficiency. However, as ignition timing in HCCI operation lacks direct actuation and is highly sensitive to operating conditions and disturbances, robust closed-loop control is necessary. LÄS MER

  4. 18. On H-infinity Control and Large-Scale Systems

    Författare :Carolina Bergeling; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; H-infinity Control; Decentralized Control; Large-Scale Systems; Infinite-Dimensional Systems;

    Sammanfattning : In this thesis, a class of linear time-invariant systems is identified for which a particular type of H-infinity optimal control problem can be solved explicitly. It follows that the synthesized controller can be given on a simple explicit form. LÄS MER

  5. 19. Modeling and Control of Plate Mill Processes

    Författare :Lars Malcolm Pedersen; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Automatiska system; robotics; control engineering; Automation; Rolling Mill. Reheat Furnace. Modeling. Identification. Control.; robotteknik; reglerteknik;

    Sammanfattning : In this thesis two processes have been modeled and controlled, namely the plate thickness control and the slab temperature control. The classical solution for the thickness control problem can't handle asymmetric hardness variations and the estimation of the controlled output introduces stability problems. LÄS MER

  7. 20. Learning to Control the Cloud

    Författare :Albin Heimerson; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cloud Computing; Reinforcement Learning; Learning-Based Control; Microservices; Datacenter; Autoscaling; Load Balancing; Neural Networks;

    Sammanfattning : With the growth of the cloud industry in recent years, the energy consumption of the underlying infrastructure is a major concern.The need for energy efficient resource management and control in the cloud becomes increasingly important as one part of the solution, where the other is to reduce the energy consumption of the hardware itself.
