  2. 1. Residual Generation Methods for Fault Diagnosis with Automotive Applications

    Author : Carl Svärd; Mattias Nyberg; Mogens Blanke; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Diagnosis; fault diagnosis; FDI; fault detection; residual; residual generation; residual generator; DAE; Systems engineering; Systemteknik;

    Abstract : The problem of fault diagnosis consists of detecting and isolating faults present in a system. As technical systems become more and more complex and the demands for safety, reliability and environmental friendliness are rising, fault diagnosis is becoming increasingly important. READ MORE

  4. 2. Fault Isolation in Distributed Embedded Systems

    Author : Jonas Biteus; Erik Frisk; Jan Eric Larsson; Linköpings universitet; []
    Keywords : Fault diagnosis; Fault isolation; Distributed diagnosis; Embedded systems; Fault tree analysis.; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : To improve safety, reliability, and efficiency of automotive vehicles and other technical applications, embedded systems commonly use fault diagnosis consisting of fault detection and isolation. Since many systems are constructed as distributed embedded systems including multiple control units, it is necessary to perform global fault isolation using for example a central unit. READ MORE

  5. 3. 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

  6. 4. A Bayesian approach to fault isolation with application to diesel engine diagnosis

    Author : Anna Pernestål; Bo Wahlberg; Stefan Arnborg; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bayesian probability; fault diagnosis; fault isolation; Bayesian inference; Automatic control; Reglerteknik;

    Abstract : Users of heavy trucks, as well as legislation, put increasing demands on heavy trucks. The vehicles should be more comfortable, reliable and safe. Furthermore, they should consume less fuel and be more environmentally friendly. For example, this means that faults that cause the emissions to increase must be detected early. READ MORE

  7. 5. Technical Language Supervision for Intelligent Fault Diagnosis

    Author : Karl Löwenmark; Fredrik Sandin; Olga Fink; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Technical Language Processing; Natural Language Processing; Intelligent Fault Diagnosis; Natural Language Supervision; Condition Monitoring; Maskininlärning; Machine Learning;

    Abstract : Condition Monitoring (CM) is widely used in industry to meet sustainability, safety, and equipment efficiency requirements. Intelligent Fault Diagnosis (IFD) research focuses on automating CM data analysis tasks, to detect and prevent machine faults, and provide decision support. READ MORE
