  1. 26. 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

  3. 27. 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

  4. 28. Extended Kalman Filter for Robust UAV Attitude Estimation

    University essay from Linköpings universitet/Reglerteknik; Linköpings universitet/Tekniska fakulteten

    Author : Martin Pettersson; [2015]
    Keywords : Kalman; autonomous; UAV; EKF; attitude; INS; IMU;

    Abstract : Attitude estimation of unmanned aerial vehicles is of great importance as it enables propercontrol of the vehicles. Attitude estimation is typically done by an attitude-heading refer-ence system (ahrs) which utilises different kind of sensors. READ MORE

  5. 29. Fault diagnosis of a Fixed Wing UAV Using Hardware and Analytical Redundancy

    University essay from Fordonssystem; Tekniska högskolan

    Author : Michael Andersson; [2013]
    Keywords : Fault Diagnosis; Model based diagnosis; Redundancy; Autopilot; UAV; fixed-wing;

    Abstract : In unmanned aerial systems an autopilot controls the vehicle without human interference. Modern autopilots use an inertial navigation system, GPS, magnetometers and barometers to estimate the orientation, position, and velocity of the aircraft. In order to make correct decisions the autopilot must rely on correct information from the sensors. READ MORE

  6. 30. Launch and recovery systems for unmannedvehicles onboard ships. A study and initialconcepts.

    University essay from KTH/Marina system

    Author : Marcus Eriksson; Patrick Ringman; [2013]
    Keywords : ;

    Abstract : This master’s thesis paper is an exploratory study along with conceptual design of launch and recovery systems(LARS) for unmanned vehicles and RHIB:s, which has been conducted for ThyssenKrupp Marine System AB inKarlskrona, Sweden. Two concepts have been developed, one for aerial vehicles (UAV:s) and one for surfaceand underwater vehicles (USV, RHIB and UUV). READ MORE
