  1. 1. On Fault Detection, Diagnosis and Monitoring for Induction Motors

    Detta är en avhandling från Luleå tekniska universitet

    Författare :Mohammed Obaid Mustafa; Luleå tekniska universitet.; [2015]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Model based fault detection and diagnosis; Model free fault detection; Set Membership Identification SMI ; Uncertainty Bounds Violation Method; Model based Support Vector Classification; Linear and Nonlinear Classification; Minimum Volume Ellipsoid method; Broken Rotor Bars; Faults of Induction Motors; Three phase induction motor; Information technology - Automatic control; Informationsteknik - Reglerteknik; Reglerteknik; Control Engineering;

    Sammanfattning : In this thesis, multiple methods and different approaches have been established and evaluated successfully, in order to detect and diagnose the faults of induction motors (IMs). The aim of this thesis is to present novel fault detection and isolation methods for the case of induction machines that would have the merit to be implemented online and being characterized by specific novel capabilities, when compared with the existing techniques.

  4. 4. Diagnosability performance analysis of models and fault detectors

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Daniel Jung; Linköpings universitet.; Linköpings universitet.; [2015]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fault detection; Fault isolation; FDI; Kullback-Leibler divergence; Engine misfire detection;

    Sammanfattning : Model-based diagnosis compares observations from a system with predictions using a mathematical model to detect and isolate faulty components. Analyzing which faults that can be detected and isolated given the model gives useful information when designing a diagnosis system. LÄS MER

  5. 5. Model-free execution monitoring in behavior-based mobile robotics

    Detta är en avhandling från Örebro : Örebro universitetsbibliotek

    Författare :Ola Pettersson; Örebro universitet.; [2004]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Datavetenskap; mobile robotics; execution monitoring; fault detection and isolation; diagnosis; data- och systemvetenskap; TECHNOLOGY Information technology Computer science; TEKNIKVETENSKAP Informationsteknik 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.
