  1. 1. Evaluation of model-based fault diagnosis combining physical insights and neural networks applied to an exhaust gas treatment system case study

    Master-uppsats, Linköpings universitet/Fordonssystem

    Författare :Björn Kleman; Henrik Lindgren; [2021]
    Nyckelord :model-based; fault diagnosis; neural networks; data-driven; Hybrid; SCR; exhaust gas treatment system; recurrent neural networks; grey-box; heavy duty truck; fault isolation; fault detection; diagnosis; urea; machine learning; Scania; structural model; MSO; residual; Fault Diagnosis Toolbox;

    Sammanfattning : Fault diagnosis can be used to early detect faults in a technical system, which means that workshop service can be planned before a component is fully degraded. Fault diagnosis helps with avoiding downtime, accidents and can be used to reduce emissions for certain applications. LÄS MER

  3. 2. Parsing and Validation of Modelica Models Utilising Fault Diagnosis

    Master-uppsats, Linköpings universitet/Fordonssystem

    Författare :Karin Lockowandt; [2017]
    Nyckelord :Model Validation; Modelica; Fault Diagnosis; Structural Analysis; XML; Dymola;

    Sammanfattning : Models have become an indispensable tool within most industrial sectors and are used to reduce costs, enhance the performance of a system etc. The computer support within modelling is extensive, whereof the programming language Modelica is eminent, especially for multi-domain models.

  4. 3. Structural Diagnosis Implementation of Dymola Models using Matlab Fault Diagnosis Toolbox

    Master-uppsats, Linköpings universitet/Fordonssystem

    Författare :Petter Lannerhed; [2017]
    Nyckelord :Diagnosis; Structural Methods; Observer Construction;

    Sammanfattning : Models are of great interest in many fields of engineering as they enable prediction of a systems behaviour, given an initial mode of the system. However, in the field of model-based diagnosis the models are used in a reverse manner, as they are combined with the observations of the systems behaviour in order to estimate the system mode.
