    Sammanfattning : Parametric signal models are used in a multitude of signal processing applications. This thesis deals with signals for which there are many candidate models, and it is not a priori known which model is the most appropriate one. LÄS MER

  2. 2. Linear Model Predictive Control : Stability and Robustness

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Johan Löfberg; Linköpings universitet.; Linköpings universitet.; [2001]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Most real systems are subjected to constraints, both on the available control effort and the controlled variables. Classical linear feedback is in some cases not enough for such systems. This has motivated the development of a more complicated, nonlinear controller, called model predictive control, MPC. LÄS MER

  3. 3. Hydromechanical simulations of wave energy conversion : Linear aspects

    Detta är en avhandling från Uppsala : Uppsala universitet

    Författare :Linnea Sjökvist; Uppsala universitet.; [2014]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Hydrodynamic simulations of buoy movement is crucial when designing a point absorbing wave power plant. The wave energy converter (WEC) that is developed in the Lysekil project by Uppsala University is studied in this thesis. LÄS MER

  4. 4. Model Reduction for Linear Time-Varying Systems

    Detta är en avhandling från Department of Automatic Control, Lund Institute of Technology (LTH)

    Författare :Henrik Sandberg; Lund University.; Lunds universitet.; [2004]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Model reduction; Linear systems; Time-varying systems; Error bounds; Frequency-domain analysis; Convergence analysis; Performance limitations; Automation; robotics; control engineering; Automatiska system; robotteknik; reglerteknik;

    Sammanfattning : The thesis treats model reduction for linear time-varying systems. Time-varying models appear in many fields, including power systems, chemical engineering, aeronautics, and computational science. They can also be used for approximation of time-invariant nonlinear models. Model reduction is a topic that deals with simplification of complex models. LÄS MER
