  1. 21. Extended and Unscented Kalman Filtering for Estimating Friction and Clamping Force in Threaded Fasteners

    University essay from Uppsala universitet/Signaler och system

    Author : Mohammad Al-Barghouthi; [2021]
    Keywords : Estimation Theory; Extended Kalman Filter; EKF; Unscented Kalman Filter; UKF; Observability; Friction; Clamping Force; Tightening; Torque Controlled; Bolt; Threaded Fasteners;

    Abstract : Threaded fasteners tend to break and loosen when exposed to cyclic loads or potent temperature variations. Additionally, if the joint is held tightly to the structure, distortion will occur under thermal expansion issues. READ MORE

  3. 22. Development of an ICP-based Global Localization System

    University essay from Linköpings universitet/Reglerteknik

    Author : Rebecka Nylén; Katherine Rajala; [2021]
    Keywords : localization; ICP; EKF; automatic control;

    Abstract : The most common way to track the position of a vehicle is by using the Global Navigation Satellite System (GNSS). Unfortunately, there are many scenarios where GNSS is inaccessible or provides low precision, and it can therefore be vulnerable to only rely on GNSS. READ MORE

  4. 23. Airborne Angle-Only Geolocalization

    University essay from Linköpings universitet/Reglerteknik

    Author : Tove Kallin; [2021]
    Keywords : Angle-only; Bearing-only; Bearing; Geolocalization; Localization; Jammers; NLS; EKF; UKF; Cramér-Rao Lower Bound; Terrain; Elevation Data;

    Abstract : Airborne angle-only geolocalization is the localization of objects on ground level from airborne vehicles (AV) using bearing measurements, namely azimuth and elevation. This thesis aims to introduce elevation data of the terrain to the airborne angle-only geolocalization problem and to demonstrate that it could be applicable for localization of jammers. READ MORE

  5. 24. Mapping an Auditory Scene Using Eye Tracking Glasses

    University essay from Linköpings universitet/Reglerteknik

    Author : Alfred Fredriksson; Joakim Wallin; [2020]
    Keywords : Sensor Fusion;

    Abstract : The cocktail party problem introduced in 1953 describes the ability to focus auditory attention in a noisy environment epitomised by a cocktail party. An individual with normal hearing uses several cues to unmask talkers of interest, such cues often lacks for people with hearing loss. READ MORE

  6. 25. Autonomous Landing of an Unmanned Aerial Vehicle on an Unmanned Ground Vehicle in a GNSS-denied scenario

    University essay from Linköpings universitet/Reglerteknik

    Author : Alexander Källström; Albin Andersson Jagesten; [2020]
    Keywords : Unmanned Aerial Vehicle; Unmanned Ground Vehicle; Autonomous Landing; Ultra-Wide Band; Proportional Navigation; GNSS-denied Scenario; Gazebo;

    Abstract : An autonomous system consisting of an unmanned aerial vehicle (UAV) in cooperation with an unmanned ground vehicle (UGV) is of interest in applications for military reconnaissance, surveillance and target acquisition (RSTA). The basic idea of such a system is to take advantage of the vehicles strengths and counteract their weaknesses. READ MORE
