  1. 1. Fault diagnosis of a variable pole-phase motor

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Claes Henriksson; [2023]
    Nyckelord :Multiphase machine; variable pole-phase machine; fault diagnosis; switch fault; phase fault; harmonic plane decomposition; wound independently controlled stator coil machine; Multifasmaskin; variabel polfasmaskin; feldiagnosticering; brytarfel; fasfel; harmonic plane decomposition; WICSC-maskin;

    Sammanfattning : Wound Independently Controlled Stator Coil (WICSC) machines are a novel type of multiphase machine with the ability to change its pole-phase configuration during operation. This enables improved post-fault control and thus prolonged continuous operation. LÄS MER

  3. 2. Visualization of Test Failure Data to Support Fault Localisation in Distributed Embedded Systems within the Automotive Industry

    Kandidat-uppsats, Göteborgs universitet/Institutionen för data- och informationsteknik

    Författare :Michael Jones; Rafael Da Silva Martins; [2017-06-22]
    Nyckelord :Fault localisation; distributed embedded systems; automotive systems; fault prediction support; continuous integration; integration testing; failure data visualisation;

    Sammanfattning : In this thesis we present the design, development and evaluation of a software tool with the purpose of assisting in the localisation of root causes of test case failures in distributed embedded systems, specifically vehicle systems controlled by a network of electronic control units (ECUs). Fault localisation is especially hard in such systems due to its distributed nature, and often organisations rely on the knowledge of in-house specialists for detecting and rectifying the underlying root cause of test case failures.

  4. 3. Architecture for Diagnostic Platform

    Uppsats för yrkesexamina på avancerad nivå, Institutionen för informationsteknologi

    Författare :Sara Hedfors; [2010]
    Nyckelord :diagnostic platform; diagnostic system; architecture; embedded system; control system;

    Sammanfattning : In order to maximize operating time of an industrial machine and minimize stand-by time, service time and operating costs, a diagnostic system can be a useful tool. Diagnostic systems employ information already available in a machine’s control system (such as control signals, system state, sensor readings and so forth) to perform intelligent fault detection and localisation, and predict future faults and service needs.
