  1. 1. Structural Diagnosis Implementation of Dymola Models using Matlab Fault Diagnosis Toolbox

    University essay from Linköpings universitet/Fordonssystem

    Author : Petter Lannerhed; [2017]
    Keywords : Diagnosis; Structural Methods; Observer Construction;

    Abstract : 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.

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

    University essay from Linköpings universitet/Fordonssystem

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

    Abstract : 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.

  3. 3. Supervision of the Air Loop in the Columbus Module of the International Space Station

    University essay from Linköpings universitet/Fordonssystem

    Author : Jasper Germeys; [2016]
    Keywords : model based diagnosis; residual generation; structural analysis; causality; automated design;

    Abstract : Failure detection and isolation (FDI) is essential for reliable operations of complex autonomous systems or other systems where continuous observation or maintenance thereof is either very costly or for any other reason not easily accessible.Beneficial for the model based FDI is that there is no need for fault data to detect and isolate a fault in contrary to design by data clustering.

  4. 4. Fault Diagnosis in Distributed Simulation Systems over Wide Area Networks using Active Probing

    University essay from Linköpings universitet/Programvara och system

    Author : Filip Andersson; [2016]
    Keywords : Active Probing; Distributed Simulation; Fault localization; Master thesis; Extensibility;

    Abstract : The domain of distributed simulation is growing rapidly. This growth leads to larger and more complex supporting network architectures with high requirements on availability and reliability. For this purpose, efficient fault-monitoring is required. READ MORE

  5. 5. Fault Detection and Diagnosis for Brine to Water Heat Pump Systems

    University essay from KTH/Tillämpad termodynamik och kylteknik

    Author : Mohammad Abuasbeh; [2016]
    Keywords : Fault detection and diagnosis; heat pumps; residuals; brine to water; model based; Principle Component Analysis;

    Abstract : The overall objective of this thesis is to develop methods for fault detection and diagnosis for ground source heat pumps that can be used by servicemen to assist them to accurately detect and diagnose faults during the operation of the heat pump. The aim of this thesis is focused to develop two fault detection and diagnosis methods, sensitivity ratio and data-driven using principle component analysis. READ MORE
