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

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Robert Hedman; [2020]
    Keywords : drone; UAV; thesis; automatic; control; VTOL;

    Abstract : 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. READ MORE

  2. 2. High-Level Control of UAV Swarms with RSSI Based Position Estimation

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Märta Paulsson; [2017]
    Keywords : Technology and Engineering;

    Abstract : Search and rescue operations can greatly benefit from the use of cooperative swarms of autonomous UAVs in order to investigate areas and collect information about the position of a missing person. In this thesis, UAV swarm algorithms are investigated where collisions are prevented both between agent pairs and between agents and static obstacles. READ MORE

  3. 3. Automatic Takeoff and Landing of Unmanned Fixed Wing Aircrafts : A Systems Engineering Approach

    University essay from Linköpings universitet/Datorteknik

    Author : Vestergren Magnus; [2016]
    Keywords : Systems Engineering; Fuzzy Logic; Fixed Wing Aircraft; Autopilot; Landing; Takeoff; UAV;

    Abstract : The purpose of this thesis is to extend an existing autopilot with automatic takeoff and landing algorithms for small fixed wing unmanned aircrafts. The work has been done from a systems engineering perspective and as for solution candidates this thesis has a bias towards solutions utilizing fuzzy logic. READ MORE

  4. 4. Cooperative Control for Landing a Fixed-Wing Unmanned Aerial Vehicle on a Ground Vehicle

    University essay from KTH/Skolan för elektro- och systemteknik (EES)

    Author : Linnea Persson; [2016]
    Keywords : ;

    Abstract : High Altitude Long Endurance (HALE) platforms are a type of Unmanned Aerial Vehicle (UAV). With their relatively easy deployment and independence of a fixed orbit, HALE UAVs have the potential to replace satellites for certain tasks in the future. READ MORE

  5. 5. Modelling and Control of a Fixed-wing UAV for Landings on Mobile Landing Platforms

    University essay from KTH/Optimeringslära och systemteori

    Author : Georg Robert Balmer; [2015]
    Keywords : ;

    Abstract : Landing on mobile landing platforms could eliminate the need for landing gear. This would particularly benefit high altitude solar UAV, which typically have a very limited payload. Such landings would however require a precise and decoupled control of the UAV’s altitude and speed. READ MORE
