  1. 1. Evaluating the accuracy of NEWA, ERA5 and NORA3 in predicting onshore wind conditions: a comparative study using ICOS meteorological mast data in Sweden

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Svetlana Kuru; [2024]
    Nyckelord :NEWA; ERA5; NORA3; wind speed; wind distribution; correlation coefficient;

    Sammanfattning : The ECMWF Reanalysis v5 (ERA5), the New European Wind Atlas (NEWA), and the 3 km Norwegian Reanalysis (NORA3) are reference datasets that are available for industry and research. The resolution of 3km in both the NORA3 and NEWA datasets sets them apart, while ERA5, with its 31km resolution, continues to serve as a reliable data source that is widely used in the industry.

  3. 2. Real-Time Certified MPC for a Nano Quadcopter

    Master-uppsats, Linköpings universitet/Institutionen för systemteknik

    Författare :Arvid Linder; [2024]
    Nyckelord :MPC; Model predictive control; quadcopter; control system;

    Sammanfattning : There is a constant demand to use more advanced control methods in a wider field of applications. Model Predictive Control (MPC) is one such control method, based on recurrently solving an optimization problem for determining the optimal control signal. LÄS MER

  4. 3. Traffic State Estimation on Swedish Highways : Model Comparison using Multisource Data

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

    Författare :Jiaqi Xu; [2023]
    Nyckelord :Traffic State Estimation; Macroscopic Traffic Model; Extended Kalman Filter; Particle Filter; Data Fusion; Trafiklägesuppskattning; Makroskopisk trafikmodell; Utökad Kalman-filter; Partikelfilter; Datafusion;

    Sammanfattning : Due to the escalating demand for traffic information and management, the significance of traffic state estimation, which involves the assessment of traffic conditions on road segments with limited measurement data, is increasing. Two primary estimation methods are model-driven and data-driven. LÄS MER

  5. 4. Performance metrics and velocity influence for point cloud registration in autonomous vehicles

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Óscar Poveda Ruiz; [2023]
    Nyckelord :autonomous vehicle; localization; registration; metrics; error; classification; estimation; autonomt fordon; lokalisering; registrering; mätvärden; fel; klassificering; uppskattning;

    Sammanfattning : Autonomous vehicles are currently under study and one of the critical parts is the localization of the vehicle in the environment. Different localization methods have been studied over the years, such as the GPS sensor, commonly fused with other sensors such as the IMU. LÄS MER

  7. 5. EV battery temperature estimation : Designing a model for minimal temperature of high-voltage battery in a BEV

    Uppsats för yrkesexamina på grundnivå, Mittuniversitetet/Institutionen för data- och elektroteknik (2023-)

    Författare :Björn Arvidsson; [2023]
    Nyckelord :BEV; temperature estimation; lowpass filter; BEV; lågpassfilter; temperaturestimering;

    Sammanfattning : Fordonsindustrin är inne i ett skifte, där förbränningsmotorer (ICE) bör-jar fasas ut och det satsas mer på eldrift med hjälp av batterier (BEV).  I detta arbete, som efterfrågades av Volvo Cars, utvecklades en matema-tisk modell som uppskattar den lägsta temperaturen i en elbils högspän-ningsbatteri.
