  1. 1. Reliability Assessment of Electro-mechanical Linear Actuator

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Raveena Dnyaneshwar Adsul; [2021]
    Keywords : Reliability assessment; FMEA; Sensitivity analysis; Tests; Tillförlitlighetsbedömning; FMEA; Känslighetsanalys; Tester;

    Abstract : Syftet med denna avhandling var att uppskatta livslängden och tillförlitligheten för det elektromekaniska linjära ställdonet genom att använda metoder för sannolikhet och statistik, med fokus på att fastställa svagare områden som kan förbättras för att inkludera dessa förbättringar i kommande generation. Bedömningen gjordes kvantitativt och kvalitativt. READ MORE

  3. 2. Design and implementation of a fault tolerant vehicle controller - an active steering approach

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Stefanos Kokogias; [2015]
    Keywords : ;

    Abstract : KTH has developed a novel Research Concept Vehicle (RCV) based on the concept of "autonomous corner modules". An autonomous corner module is basically a wheel with a built-in electric hub motor, and additional actuators to tilt and yaw the wheel. One module is attached at each of the four corners of a 'skateboard' chassis. READ MORE

  4. 3. A model-parameter invariant approach to HVAC fault detection and diagnosis

    University essay from KTH/Reglerteknik

    Author : Dario Papale; [2012]
    Keywords : ;

    Abstract : This thesis develops and experimentally evaluates a model-based detector for detecting actuator failures in HVAC systems which dynamically estimates the model parameters while performing detection. Specifically, this thesis considers actuator failures which result in the actuator valve sticks in an unknown (but constant) position. READ MORE

  5. 4. A model-based approach to HVAC fault detection and diagnosis

    University essay from KTH/Reglerteknik

    Author : Francesca Madia Mele; [2012]
    Keywords : ;

    Abstract : This thesis develops and experimentally evaluates a sequential model-based detector for detecting actuator failures in HVAC systems. Specifically, this thesis considers actuator failures which result in the actuator valve sticks in an unknown (but constant) position. READ MORE
