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. Implementing Kalman Filtering Algorithms for Estimating Clamp Force on a Test Rig : Testing the Power and Limitations of Unscented Kalman Filter-based Estimations

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

   Författare :Tim Naser; [2023]
   Nyckelord :Clamping Froce; Kalman Filtering; Unscented Kalman Filtering; Tightening; Consequence of User Errors During Tightening; Velocity Profiles; Klämkraft; Kalman Filtrering; Unscented Kalman Filtrering; Åtdragning; Konsekvens av Användarfel Under Åtdragning; Hastightersprofiler.;

   Sammanfattning : his study explores clamp force estimation using Unscented Kalman Filtering (UKF) in torque-controlled tightening scenarios with various velocity profiles. Previous research has explored the impact of velocity levels on target torque and clamping force, but only using hand-held tools. 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. GPS and IMU Sensor Fusion to Improve Velocity Accuracy

   Kandidat-uppsats, Uppsala universitet/Institutionen för elektroteknik

   Författare :Adam Laurell; Erik Karlsson; Yousuf Naqqar; [2022]
   Nyckelord :Sensor fusion; GPS navigation; Extended Kalman filter; Control systems; Velocity estimation; Data processing;

   Sammanfattning : The project explores the possibilities on how to improve the accuracy of GPS velocity data by using sensor fusion with an extended Kalman filter. The proposed solution in this project is a sensor fusion between the GPS and IMU of the system, where the extended Kalman filter was used to estimate the velocity from the sensor data. LÄS MER

7. 5. Modeling and Control of a PMSM Operating in Low Speeds

   Master-uppsats, Linköpings universitet/Fordonssystem

   Författare :Robin Helsing; Tobias Sanchez; [2022]
   Nyckelord :PMSM; BLDC; low speed; EKF; UKF; MPC; Extended Kalman Filter; Unscented Kalman Filter; PI; Control; FOC;

   Sammanfattning : A permanent magnet synchronous motor is a type of motor that is used in several different application areas, not least in an autonomous robots where it is the motor that drives the wheels. Today, many actors choose simulation as a tool to save money and time when product tests are performed. LÄS MER
