  1. 11. 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. 12. 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. 13. 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. 14. Smartphone Based Indoor Positioning Using Wi-Fi Round Trip Time and IMU Sensors

    University essay from Linköpings universitet/Institutionen för datavetenskap

    Author : Gustav Aaro; [2020]
    Keywords : Wi-Fi RTT; Indoor positioning; FTM; Android; Smartphone; Sensor fusion; IPS;

    Abstract : While GPS long has been an industry standard for localization of an entity or person anywhere in the world, it loses much of its accuracy and value when used indoors. To enable services such as indoor navigation, other methods must be used. A new standard of the Wi-Fi protocol, IEEE 802. READ MORE

  6. 15. Improvement of an existing Integrated Vehicle Dynamics Control System influencing an urban electric car

    University essay from KTH/Flygdynamik

    Author : Arihant Sureka; [2020]
    Keywords : model predicitve control; MPCA; vehicle dynamics; Single track model; Rear wheel steering; kalametric; state estimation; design matrix; aliasing; kalman filter; projectionalgorithm; resolution; model predicitve control; MPCA; kalametric; tillståndsestimering; designmatris; vikningsdistorsion; kalmanfilter; projection algorithm; upplösning;

    Abstract : The Integrated Vehicle Dynamics Control (IVDC) concept can influence the vehicle behaviour both longitudinally and laterally with just one upper level control concept and further lower level controllers. This demands for state estimation of the vehicle which also includes estimating parameters of interest for the vehicle dynamicist. READ MORE
