1. 6. Local voltage control in a low voltage grid with high photovoltaic penetration

   University essay from Lunds universitet/Institutionen för reglerteknik

   Author : Joakim Bakklund; [2024]
   Keywords : Technology and Engineering;

   Abstract : This thesis examines how active power control (Volt-Watt control) and reactive power compensation (Volt-VAr control) can help limit voltage increases on the low voltage grid due to high photovoltaic (PV), installations. Due to the large increase in interest to install small scale PV-systems within residential areas the Distribution System Operator E. READ MORE

3. 7. Robust Aircraft Positioning using Signals of Opportunity with Direction of Arrival

   University essay from Linköpings universitet/Reglerteknik

   Author : Erik Axelsson; Sebastian Fagerstedt; [2023]
   Keywords : Simultaneous localisation and mapping; direction of arrival; signals of opportunity; extended Kalman filter; positioning;

   Abstract : This thesis considers the problem of using signals of opportunity (SOO) with known direction of arrival (DOA) for aircraft positioning. SOO is a collective name for a wide range of signals not intended for navigation but which can be intercepted by the radar warning system on an aircraft. READ MORE

4. 8. Collaborative Mapping with Drone Swarms Utilizing Relative Distance Measurements

   University essay from Linköpings universitet/Reglerteknik

   Author : Johan Forsman; Carl Tidén; [2023]
   Keywords : ;

   Abstract : The field of use for unmanned aerial vehicles, UAVs, has completely exploded in the last decade. Today they are used for surveillance missions and inspecting places that are difficult for people to access. To increase the efficiency and robustness in the execution of these types of missions, swarms of cooperating drones can be used. READ MORE

5. 9. Sensorless Hybrid Field-Oriented Control Two-Phase Stepper Motor Driver

   University essay from Linköpings universitet/Reglerteknik

   Author : Emil Lydell; [2023]
   Keywords : Stepper motor; Field-Oriented Control; FOC; Driver; Two-Phase; 2-Phase;

   Abstract : Hybrid stepper motors are small electrical motors with high torque production, compared with other electrical motors of the same size. Hybrid stepper motors are reliable in open-loop systems, in Sinusoidal mode, but with a drawback of high power consumption. READ MORE

6. 10. Visual-Inertial SLAM Using a Monocular Camera and Detailed Map Data

   University essay from Linköpings universitet/Reglerteknik

   Author : Viktor Ekström; Ludvig Berglund; [2023]
   Keywords : SLAM; localisation; monocular camera; GTSAM; factor graphs; iSAM2;

   Abstract : The most commonly used localisation methods, such as GPS, rely on external signals to generate an estimate of the location. There is a need of systems which are independent of external signals in order to increase the robustness of the localisation capabilities. READ MORE
