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

    Author : Mattias Nyberg; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : 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. READ MORE

  4. 2. Model Based Diagnosis and Supervision of Industrial Gas Turbines

    Author : Emil Larsson; Jan Åslund; Erik Frisk; Lars Eriksson; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Supervision of performance in gas turbine applications is important in order to achieve: (i) reliable operations, (ii) low heat stress in components, (iii) low fuel consumption, and (iv) efficient overhaul and maintenance. To obtain good diagnosis performance it is important to have tests which are based on models with high accuracy. READ MORE

  5. 3. Model Based Vehicle Level Diagnosis for Hybrid Electric Vehicles

    Author : Christofer Sundström; Lars Nielsen; Erik Frisk; Linköpings universitet; []
    Keywords : ;

    Abstract : When hybridizing a vehicle, new components are added that need to be monitored due to safety and legislative demands. Diagnostic aspects due to powertrain hybridization are investigated, such as that there are more mode switches in the hybrid powertrain compared to a conventional powertrain, and that there is a freedom in choosing operating points of the components in the powertrain via the overall energy management and still fulfill the driver torque request.

  6. 4. Behavioral and Structural Model Based Approaches to Discrete Diagnosis

    Author : Magnus Larsson; Lennart Ljung; Inger Klein; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The basic motivation for this thesis is the fact that things go wrong. With the growing complexity of todays engineering systems, the need has arisen for systematic approaches to failure diagnosis, i.e., fault detection and isolation. READ MORE

  7. 5. Model-based control and monitoring of the flotation process

    Author : Benny Stenlund; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reglerteknik; Control Engineering;

    Abstract : In the mineral processing industry, flotation constitutes the most important technique for extraction of the valuable minerals from the ore. This process involves both chemical and physical parts, the theory of which are not yet completely understood. READ MORE
