  1. 1. Lithium-ion battery modeling and SoC estimation

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

    Författare :Ruoyu Xu; [2023]
    Nyckelord :lithium-ion battery; cell modeling; state of charge; extended Kalman filter; pack modeling; litiumjonbatteri; cellmodellering; laddningstillstånd; utökat Kalmanfilter; packmodellering;

    Sammanfattning : The energy crisis and environmental pollution have become increasingly prominent in recent years. Lithium batteries have attracted extensive attention due to their high energy density, safety, and low pollution. To further study how the battery works, it is necessary to establish an accurate model conforming to the battery characteristics. LÄS MER

  3. 2. The Effect of Simulink Block Kalman Filters in a CubeSat ADCS

    Master-uppsats, KTH/Rymdteknik

    Författare :Jesper Larsson; [2020]
    Nyckelord :ADCS; Kalman Filter; Simulink; Simulation; Block; EKF; UKF; ADCS; Kalmanfilter; Simulink; Simulering; Block; EKF; UKF;

    Sammanfattning : The purpose of this paper was to implement Kalman filtering in the form of pre-existing Simulink blocks into a CubeSat attitude determination and control system simulation and to evaluate their performance. In recent versions of Simulink, the block library has been expanded, providing a new level of abstraction for simulation engineers. LÄS MER

  4. 3. Efficient and Robust Attitude Determination and Control System Design for the MIST CubeSat

    Master-uppsats, KTH/Rymdteknik

    Författare :Federico Raiti; [2018]
    Nyckelord :;

    Sammanfattning : This thesis investigated different configurations of the attitude determination and control system (ADCS) for the MIST satellite, to find a satisfying trade-off between computational demand and estimation/pointing accuracy. A model of the satellite dynamics was developed and used in a simulation. LÄS MER

  5. 4. Estimation of Engine Inlet Air Temperature in Fighter Aircraft

    Master-uppsats, Linköpings universitet/Reglerteknik

    Författare :Gustav Sandvik; [2018]
    Nyckelord :system identification; grey box modeling; engine inlet temperature; heat transfer; fighter aircraft;

    Sammanfattning : An accurate estimate of the gasturbine inlet air temperature is essential to the stability of the engine since its control depends on it. Most supersonic military aircrafts have a design with the engine integrated in the fuselage which requires a rather long inlet duct from the inlet opening to the engine face. LÄS MER

  7. 5. Feasibility Study of Indoor Positioning in a Hospital Environment Using Smartphone Sensors

    Master-uppsats, Linköpings universitet/Reglerteknik

    Författare :Joakim Skytte; [2017]
    Nyckelord : Indoor positioning ; smartphone; IMU; Wi-Fi; Dead Reckoning ; Inomhuspositionering; tröghetsnavigering; wifi;

    Sammanfattning : This thesis is a feasibility study of contemporary indoor positioning approaches in an hospital environment using sensor available on Android phones together with Wi-Fi fingerprintingand map information. The purpose is to determine the resolution of pedestrian indoor positioning and whether it is sufficient for room level accuracy. LÄS MER
