    Författare :Johan Sjöberg; Torkel Glad; Xiaoming Hu; Linköpings universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Optimal Control; Descriptor Systems; Differential-Algebraic Systems; Controllability Function; Observability Function; Automatic control; Reglerteknik;

    Sammanfattning : I denna avhandling studeras optimal återkopplad styrning av olinjära deskriptorsystem. Ett deskriptorsystem är en matematisk beskrivning som kan innehålla både differentialekvationer och algebraiska ekvationer. LÄS MER

  2. 2. Power System Damping - Structural Aspects of Controlling Active Power

    Författare :Olof Samuelsson; Industriell elektroteknik och automation; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electronics and Electrical technology; controller interaction; mode controllability; mode observability; mechanical equivalent; linear differential-algebraic equations; modal analysis; active power; power system damping; electro-mechanical oscillations; Elektronik och elektroteknik; Automation; robotics; control engineering; Automatiska system; robotteknik; reglerteknik;

    Sammanfattning : Environmental and economical aspects make it difficult to build new power lines and to reinforce existing ones. The continued growth in demand for electric power must therefore to a great extent be met by increased loading of available lines. LÄS MER

  3. 3. Model Error Compensation in ODE and DAE Estimators : with Automotive Engine Applications

    Författare :Erik Höckerdal; Erik Frisk; James Peyton-Jones; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Information technology; Informationsteknik; Automatic control; Reglerteknik;

    Sammanfattning : Control and diagnosis of complex systems demand accurate information of the system state to enable efficient control and to detect system malfunction. Physical sensors are expensive and some quantities are hard or even impossible to measure with physical sensors. This has made model-based estimation an attractive alternative. LÄS MER

  4. 4. Observer Design and Model Augmentation for Bias Compensation with Engine Applications

    Författare :Erik Höckerdal; Erik Frisk; Tomas McKelvey; Linköpings universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Estimation; observer; bias compensation; diesel engine; EKF; Automatic control; Reglerteknik;

    Sammanfattning : Control and diagnosis of complex systems demand accurate knowledge of certain quantities to be able to control the system efficiently and also to detect small errors. Physical sensors are expensive and some quantities are hard or even impossible to measure with physical sensors. This has made model-based estimation an attractive alternative. LÄS MER

  5. 5. Strategies and maladaptive behaviours in complex dynamic decision making

    Författare :Anders Jansson; Uppsala universitet; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; Psychology; Dynamic decision making; complex problem solving; mental models; Psykologi; Psychology; Psykologi; Psychology; psykologi;

    Sammanfattning : Research on dynamic decision making using so called microworlds has followed two differentapproaches: the German approach of "komplexes Problemlösen" where the central problem has beenseen as that of action control and the dynamic decision making approach, where the central problemhas been seen as that of task control, In this thesis, these approaches are combined in order to seehow people regulate their behaviour so that they can manage to control a complex, opaque anddynamic decision task. The general objective of the thesis is to see how people develop mentalmodels and formulate goals as a function of observability and action possibilities. LÄS MER
