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

   University essay from Linköpings universitet/Institutionen för systemteknik

   Author : Simon Saber; [2024]
   Keywords : model-based diagnostics; modellbaserad diagnostik;

   Abstract : 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. State of Health estimation of battery systems

   University essay from Lunds universitet/Institutionen för reglerteknik

   Author : Carl Spångberg; [2023]
   Keywords : Technology and Engineering;

   Abstract : This study focuses on estimating the state of health (SoH) of a lithium iron phosphate (LFP) battery system, which is crucial for assessing the value and lifespan of new or used batteries in energy storage, grid support, and electric vehicle applications. A proposed method for determining SoH based on comparing useful and nominal useful capacities in Ah and Wh, as well as total and nominal capacity, has been presented. READ MORE

4. 3. Exploiting the Overtones in Online Localization of Sound Sources

   University essay from Lunds universitet/Matematisk statistik

   Author : David Sundström; [2022]
   Keywords : Multi-pitch estimation; localization; block sparsity; sparse recursive least squares; online estimation; ADMM; adaptive dictionary; Mathematics and Statistics;

   Abstract : Localization of multiple sound sources from a microphone array is a challenging task that has been a research topic for decades. The challenges stem from the diversity of acoustic contexts due to reverberation and disturbances. READ MORE

5. 4. Torque-Based Load Estimation for Passenger Vehicles

   University essay from Linköpings universitet/Reglerteknik

   Author : Tobias Nyberg; [2021]

   Abstract : An accurate estimate of the mass of a passenger vehicle is important for several safety systems and environmental aspects. In this thesis, an algorithm for estimating the mass of a passenger vehicle using the recursive least squares methodis presented. READ MORE

6. 5. Adaptive PI-control for an air sterilization module

   University essay from Lunds universitet/Institutionen för reglerteknik

   Author : Henrik Stålbom; [2020]
   Keywords : Technology and Engineering;

   Abstract : The goal of this master thesis has been to implement adaptive PI-control of two air flow heaters in an air sterilization module. This is done by modeling the module and using the information from the model to estimate the dynamics of the heaters. READ MORE
