  1. 1. Battery Degradation and Health Monitoring in Lithium-Ion Batteries: An Evaluation of Parameterization and Sensor Fusion Strategies

    Master-uppsats, Linköpings universitet/Institutionen för systemteknik

    Författare :Simon Saber; [2024]
    Nyckelord :model-based diagnostics; modellbaserad diagnostik;

    Sammanfattning : The purpose of this project was to perform model-based diagnosis on Li-ion batteries using real-world data and sensor fusion algorithms. The data used in this project was collected and distributed by NASA and mainly consists of voltage and current measurements collected on numerous batteries that were repeatedly charged and discharged from their beginning of life, and until surpassing their end of life.

  3. 2. Blind Acoustic Feedback Cancellation for an AUV

    Master-uppsats, Linköpings universitet/Reglerteknik

    Författare :Hampus Frick; [2023]
    Nyckelord :acoustical feedback; adaptive filter; least leaky mean square; Kalman; blind source separation; independent component analysis; complex independent component analysis; degenerative unmixing estimation technique; convolutive mixture;

    Sammanfattning : SAAB has developed an autonomous underwater vehicle that can mimic a conventional submarine for military fleets to exercise anti-submarine warfare. The AUV actively emits amplified versions of received sonar pulses to create the illusion of being a larger object. LÄS MER

  4. 3. Airspeed estimation of aircraft using two different models and nonlinear observers

    Master-uppsats, Linköpings universitet/Fordonssystem

    Författare :Alexander Roser; Anton Thunberg; [2023]
    Nyckelord :sensor fusion; flight mechanics; Kalman filter; extended Kalman filter; unscented Kalman filter; pitot tube; airspeed estimation; simulation;

    Sammanfattning : When operating an aircraft, inaccurate measurements can have devastating consequences. For example, when measuring airspeed using a pitot tube, icing effects and other faults can result in erroneous measurements. LÄS MER

  5. 4. The Implementation and Evaluation of Learning Approaches to State Filtering

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Anna Wilhelmsson; [2022]
    Nyckelord :;

    Sammanfattning : State estimation uses measurements of a system’s output to estimate the state. A particular method within state estimation is filtering, which estimates the state using measurements up to and including the current time. LÄS MER

  7. 5. Load Weighing for Underground Mining Machines

    Master-uppsats, Linköpings universitet/Institutionen för systemteknik

    Författare :Axel Ståhlbom; [2022]
    Nyckelord :Kalman filter; EKF; load weiging; LHD; mining; load estimation; mass estimation;

    Sammanfattning : The goal of this work was to calculate the mass in the bucket of a underground loaderfrom pressure data in the cylinders. Three different approaches to using a Kalman filter toestimate the loaded mass were tried and evaluated in MATLAB simulations. LÄS MER
