  1. 11. Model Based Fault Diagnosis : Methods, Theory, and Automotive Engine Applications

    Författare :Mattias Nyberg; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Model based fault diagnosis is to perform fault diagnosis by means of models. An important question is how to use the models to construct a diagnosis system. To develop a general theory for this, useful in real applications, is the topic of the first part of this thesis. LÄS MER

    Författare :Dorothée Vallot; Rickard Pettersson; Veijo Pohjola; Ken Mattsson; Tómas Jóhannesson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cryospheric science; glacier modelling; time-lapse imagery; undercutting; sliding inversion; discrete particle model; calving model; subglacial hydrology; sliding law; automatic detection method; calving events size and frequency; ocean interaction; melt water runoff; ice dynamics; ice flow model; Geovetenskap med inriktning mot naturgeografi; Earth Science with specialization in Physical Geography;

    Sammanfattning : Future sea level rise associated to global warming is one of the greatest societal and environmental challenges of tomorrow. A large part of the contribution comes from glaciers and ice sheets discharging ice and meltwater into the ocean and the recent worldwide increase is worrying. LÄS MER

  4. 13. Optimal Control and Model Reduction of Nonlinear DAE Models

    Författare :Johan Sjöberg; Torkel Glad; Xiaoming Hu; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; DAE Models; Optimal Control; Model Reduction; Automatic control; Reglerteknik;

    Sammanfattning : In this thesis, different topics for models that consist of both differential and algebraic equations are studied. The interest in such models, denoted DAE models, have increased substantially during the last years. LÄS MER

  5. 14. Analytic Parameterization of Stabilizing Controllers for the Moore-Greitzer Compressor Model

    Författare :Alina Andersson; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nonlinear control; Moore-Greitzer compressor model; Dynamic output feedback; Compressors; Nonlinear control systems; Stability robustness; Constraints; Nonlinearity; Lyapunov stability;

    Sammanfattning : This work presents an extension, simplification and application of a design procedure for dynamic output feedback design for systems with nonlinearities satisfying quadratic constraints (QC). Our method was motivated by the challenges of output feedback control design for the three-state Moore-Greitzer (MG) compressor model. LÄS MER

  7. 15. Modeling, Model Validation and Uncertainty Identification for Power System Analysis

    Författare :Tetiana Bogodorova; Luigi Vanfretti; Konstantin Turitsyn; Francisco Gonzalez-Longatt; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Power system modelling; model validation; parameter identification; uncertainty identification; Modelica; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : It is widely accepted that correct system modeling and identification are among the most important issues power system operators face when managing instability and post-contingency scenarios. The latter is usually performed involving special computational tools that allow the operator to forecast, prevent system failure and take appropriate actions according to protocols for different contingency cases in the system.
