  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. 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

  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. READ MORE

  4. 4. Force Feedback Control of a Semi-Active Shock Absorber

    University essay from Linköpings universitet/ReglerteknikLinköpings universitet/Tekniska högskolan

    Author : Per Svennerbrandt; [2014]
    Keywords : Force feedback control; semi-active dampers; damper modeling; exact linearization;

    Abstract : Semi-active suspension systems promise to significantly reduce the necessary trade-off be-tween handling and passenger comfort present in conventional suspension systems by enabling active chassis and wheel control. Öhlins Racing AB have developed a semi-active suspension technology known as CES, Continuously controlled Electronic Suspension, based on solenoid control valves which are integrated into specially designed hydraulic dampers, and are currently developing control and estimation systems which will enable their application in advanced motorcycle suspensions.
