  1. 1. Further Development of a Distributed Robust Control Approach towards a Nanosatellite Formation Flying Application

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Johannes Dauner; [2020]
    Nyckelord :NetSat; CubeSat; Nanosatellite; Satellite Formation; Control; Robust Control; Distributed Control;

    Sammanfattning : This thesis proposes a distributed robust control approach for low-thrust nanosatellite formation flying. The presented control approach is the further development of an already existing approach which combines robust control and distributed control using the consensus approach. LÄS MER

  2. 2. Robust control system development forVTOL-to-fixed wing flight transition withthe EcoSoar UAV : A masters thesis in Automatic Control

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Robert Hedman; [2020]
    Nyckelord :drone; UAV; thesis; automatic; control; VTOL;

    Sammanfattning : A non switching, non linear, quaternion based attitude P2 controller, together with a sensitivitynormalizing function for the control surfaces has been simulated and implemented on a flying fixedwing with non vectored engines. In simulations the controller worked well in all flight modes,hovering, transition and flying, and also rejected a simple wind disturbance in all modes. LÄS MER

  3. 3. Bending modes analysis in atmospheric flight for heavy launcher

    Master-uppsats, KTH/Flygdynamik

    Författare :Valentin Pothier; [2019]
    Nyckelord :;

    Sammanfattning : This report presents the bending modes study conducted on a heavy launcher. The controller of the launcher takes as inputs the attitude and attitude rate measurements given by the Inertial Measurement Unit (IMU). LÄS MER

  4. 4. Autonomous control of unmanned aerial multi-agent networks in confined spaces

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknik

    Författare :Sebastian Green; Pontus Månsson; [2019]
    Nyckelord :Technology and Engineering;

    Sammanfattning : In this thesis, the functionality of existing Crazyflie models is extended to include current implementations of attitude and velocity control. The models are validated both as individual agents and as a swarm through comparisons of swarm behaviour during step, ramp and frequency response testing. LÄS MER

  5. 5. Gyro Stabilization of a Positioning Unit

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknik

    Författare :Wilhelm Andrén; Ella Hjertberg; [2019]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Mounting cameras on motorized objects has become possible in greater extent due to the emerging camera technology during the past few decades. This application could prove useful in several areas such as search and rescue operations, surveillance or even news monitoring. LÄS MER
