  2. 1. Optimization of Unmanned Aerial Vehicles : Expanding the Multidisciplinary Capabilities

    Author : Athanasios Papageorgiou; Johan Ölvander; Mehdi Tarkian; Kristian Amadori; Mikael Thellner; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Over the last decade, Unmanned Aerial Vehicles (UAVs) have experienced an accelerated growth, and nowadays they are being deployed in a variety of missions that have traditionally been covered by manned aircraft. This unprecedented market expansion has created new and unforeseen challenges for the manufacturing industry which is now called to further reduce the idea-to-market times while simultaneously delivering designs of even higher performance.

  4. 2. Positioning Algorithms for Surveillance Using Unmanned Aerial Vehicles

    Author : Per-Magnus Olsson; Patrick Doherty; Lars Karlsson; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Unmanned aerial vehicles; surveillance; communication relay; label- correcting; dual ascent; Steiner trees; Computer science; Datalogi;

    Abstract : Surveillance is an important application for unmanned aerial vehicles (UAVs). The sensed information often has high priority and it must be made available to human operators as quickly as possible. Due to obstacles and limited communication range, it is not always possible to transmit the information directly to the base station. READ MORE

  5. 3. Vision-Based Localization and Guidance for Unmanned Aerial Vehicles

    Author : Gianpaolo Conte; Patrick Doherty; Rod Walker; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Unmanned Aerial Vehicles; Guidance; Kalman filter; Vision-based Navigation; Geo-referenced Imagery; Autonomous Landing; Target Geo-location; Computer science; Datavetenskap;

    Abstract : The thesis has been developed as part of the requirements for a PhD degree at the Artificial Intelligence and Integrated Computer System division (AIICS) in the Department of Computer and Information Sciences at Linköping University.The work focuses on issues related to Unmanned Aerial Vehicle (UAV) navigation, in particular in the areas of guidance and vision-based autonomous flight in situations of short and long term GPS outage.

  6. 4. Nonlinear Control of Unmanned Aerial Vehicles : Systems With an Attitude

    Author : Marcus Greiff; Institutionen för reglerteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nonlinear Control; Lyapunov Methods; Aerospace; Aerial Vehicles; Output Feedback; Control Theory;

    Abstract : This thesis deals with the general problem of controlling rigid-body systems through space, with a special focus on unmanned aerial vehicles (UAVs). Several promising UAV control algorithms have been developed over the past decades, enabling truly astounding feats of agility when combined with modern sensing technologies. READ MORE

  7. 5. On the utilization of Nonlinear MPC for Unmanned Aerial Vehicle Path Planning

    Author : Björn Lindqvist; George Nikolakopoulos; Dimos Dimarogonas; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Unmanned Aerial Vehicles; Obstacle Avoidance; Collision Avoidance; Nonlinear MPC; Model Predictive Control; Multi-agent Systems; Dynamic Obstacles; Robotics and Artificial Intelligence; Robotik och artificiell intelligens;

    Abstract : This compilation thesis presents an overarching framework on the utilization of nonlinear model predictive control(NMPC) for various applications in the context of Unmanned Aerial Vehicle (UAV) path planning and collision avoidance. Fast and novel optimization algorithms allow for NMPC formulations with high runtime requirement, as those posed by controlling UAVs, to also have sufficiently large prediction horizons as to in an efficient manner integrate collision avoidance in the form of set-exclusion constraints that constrain the available position-space of the robot.
