  1. 1. Fault Isolation in Distributed Embedded Systems

    University dissertation from Institutionen för systemteknik

    Author : Jonas Biteus; Erik Frisk; Jan Eric Larsson; [2007]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 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

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

    University dissertation from Linkö : Linköping University Electronic Press

    Author : Carl Svärd; Mattias Nyberg; Mogens Blanke; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Diagnosis; fault diagnosis; FDI; fault detection; residual; residual generation; residual generator; DAE; TECHNOLOGY Information technology Systems engineering; TEKNIKVETENSKAP Informationsteknik 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

  3. 3. Residual generation for fault diagnosis

    University dissertation from Linköping : Linköpings universitet

    Author : Erik Frisk; Lars Nielsen; [2001]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : 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. READ MORE
