  1. 6. Residual generation for fault diagnosis

    Författare :Erik Frisk; Lars Nielsen; Linköpings universitet; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : The objective when supervising technical processes is to alarm an operator when a fault is detected and also identify one, or possibly a set of components, that may have been the cause of the alarm. Diagnosis is an expansive subject, partly due to the fact that nowadays, more applications have more embedded computing power and more available sensors than before. LÄS MER

  3. 7. Design and Analysis of Diagnosis Systems Using Structural Methods

    Författare :Mattias Krysander; Mattias Nyberg; Jan Lunze; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; diagnosis; graph theory; structual methods; algorithms; fault isolation; complete; sound; Systems engineering; Systemteknik;

    Sammanfattning : In complex and automated technological processes the effects of a fault can quickly propagate and lead to degradation of process performance or even worse to a catastrophic failure. This means that faults have to be found as quickly as possible and decisions have to be made to stop the propagation of their effects and to minimize process performance degradation. LÄS MER

  4. 8. Methods for Automated Design of Fault Detection and Isolation Systems with Automotive Applications

    Författare :Carl Svärd; Mattias Nyberg; Erik Frisk; Mattias Krysander; Vincent Cocquempot; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Fault detection and isolation (FDI) is essential for dependability of complex technical systems. One important application area is automotive systems, where precise and robust FDI is necessary in order to maintain low exhaust emissions, high vehicle up-time, high vehicle safety, and efficent repair.

  5. 9. Advances on Adaptive Fault-Tolerant System Components: Micro-processors, NoCs, and DRAM

    Författare :Alirad Malek; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Network-on-Chip; Quality-of-Service; Main memory; Micro-processors; Error-Correcting Codes; Reliability analysis; Adaptive fault tolerance;

    Sammanfattning : The adverse effects of technology scaling on reliability of digital circuits have made the use of fault tolerance techniques more necessary in modern computing systems. Digital designers continuously search for efficient techniques to improve reliability, while keeping the imposed overheads low. LÄS MER

  7. 10. Model-free execution monitoring in behavior-based mobile robotics

    Författare :Ola Pettersson; Alessandro Saffiotti; Lars Karlsson; Joachim Hertzberg; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Datavetenskap; mobile robotics; execution monitoring; fault detection and isolation; diagnosis; data- och systemvetenskap; Computer science; Datavetenskap; Computer and Systems Science; Data- och systemvetenskap;

    Sammanfattning : In the near future, autonomous mobile robots are expected to assist us by performing service tasks in many different areas, including transportation, cleaning, mining, or agriculture. In order to manage these tasks in a changing and partially unpredictable environment, without the help of humans, the robot must have the ability to plan its actions and to execute them robustly and in a safe way.
