1. 21. Online trajectory planning and observer based control

   Författare :David A. Anisi; Xiaoming Hu; Daizhan Cheng; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computational Optimal Control; Receding Horizon Control; Mission Uncertainty; Safety; Task Completion; Consensus Problem; Simultaneous Arrival; Adaptive Grid Methods; Missile Guidance; Nonlinear Observer Design; Active Observers; Non--uniformly Observable Systems; Mobile Robotic Systems; Intrinsic Observers; Differential Geometric Methods; Euler-Lagrange Systems; Contraction Analysis.; Optimization; systems theory; Optimeringslära; systemteori;

   Sammanfattning : The main body of this thesis consists of four appended papers. The first two consider different aspects of the trajectory planning problem, while the last two deal with observer design for mobile robotic and Euler-Lagrange systems respectively. LÄS MER

3. 22. Improving Fixed Wing UAV Endurance, by Cooperative Autonomous Soaring

   Författare :Klas Andersson; Petter Ögren; Fredrik Bruhn; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; UAV; Autonomous soaring; Cooperative soaring; Computer Science; Datalogi; Flyg- och rymdteknik; Aerospace Engineering;

   Sammanfattning : The ever-expanding use and development of smaller UAVs (Unmanned Aerial Vehicles) has highlighted an increasing demand for extended range and endurance for this type of vehicles. In this thesis, the development of a concept and system for autonomous soaring of cooperating unmanned aerial vehicles is presented.

4. 23. Coordination of Multi-Agent Systems: Predictive and Vision-based Control for Aerial and Space Robotics

   Författare :Pedro Roque; Dimos V. Dimarogonas; Mikael Johansson; Soon-Jo Chung; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Aerial and space autonomous systems are safety-critical systems that need to operate safely and reliably for long periods of time. Their applications range from autonomous inspection of complex and sensitive structures, to surveillance and transportation of sensitive payloads. LÄS MER

5. 24. Operational Military Violence : A Cartography of Bureaucratic Minds and Practices

   Författare :Anders Malm; Marie Demker; Dan Öberg; Annika Bergman-Rosamond; Försvarshögskolan; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; military violence; bureaucratisation; operational level; targeting; military masculinity; Krigsvetenskap; Krigsvetenskap; military violence; bureaucratisation; operational level; targeting; military masculinity;

   Sammanfattning : Western use of military violence is becoming increasingly centralised, partly through the use of Unmanned Aerial Vehicles (or more commonly referred to as “drones” in the literature). Drone technology allows control and command of military operations to be put under one roof, and as military organisations traditionally have a close dependence on technological developments, procedures and regulations for centralised command and control have developed in close concert with advances in drone technology.

7. 25. One Image, Many Insights: A Synergistic Approach Towards Enabling Autonomous Visual Inspection

   Författare :Vignesh Kottayam Viswanathan; George Nikolakopoulos; Dimitrios Kanoulas; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Unified autonomy; aerial robotics; space robotics; Robotics and Artificial Intelligence; Robotik och artificiell intelligens;

   Sammanfattning : Visual inspection in autonomous robotics is a task in which autonomous agents are required to gather visual information of objects of interest, in a manner that ensures safety, efficiency and comprehensive coverage. It is, therefore, crucial for identifying key landmarks, detecting cracks or defects, or reconstructing the observed object for detailed analysis. LÄS MER
