4. 2. Model Predictive Control for Cooperative Rendezvous of Autonomous Unmanned Vehicles

   Author : Linnea Persson; Bo Wahlberg; Jonathan How; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Autonomous systems; Model Predictive Control; MPC; Autonomous landing; UAV; Unmanned Aerial Vehicle; Moving target; Quadcopter; Implementation; Variable Horizon MPC; Adaptive Horizon MPC; Autonom landning; Modell-prediktiv reglerteknik; quadcopter; autonoma system; MPC; Electrical Engineering; Elektro- och systemteknik;

   Abstract : This thesis investigates cooperative maneuvers for aerial vehicles autonomously landing on moving platforms. The objective has been to develop methods for safely performing such landings on real systems subject to a variety of disturbances, as well as physical and computational constraints. READ MORE

5. 3. Autonomous and Cooperative Landings Using Model Predictive Control

   Author : Linnea Persson; Bo Wahlberg; Tor Arne Johansen; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cooperative control; autonomous landings; rendezvous; UAV; drone; USV; Electrical Engineering; Elektro- och systemteknik;

   Abstract : Cooperation is increasingly being applied in the control of interconnected multi-agent systems, and it introduces many benefits. In particular, cooperation can improve the efficiency of many types of missions, and adds flexibility and robustness against external disturbances or unknown obstacles. READ MORE

6. 4. Increasing Autonomy of Unmanned Aircraft Systems Through the Use of Imaging Sensors

   Author : Piotr Rudol; Andrzej Szalas; Pascual Campoy; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; UAV; UAS; UAV autonomy; human-body detection; color-thermal image fusion; vehicle tracking; geolocation; UAV indoor navigation;

   Abstract : The range of missions performed by Unmanned Aircraft Systems (UAS) has been steadily growing in the past decades thanks to continued development in several disciplines. The goal of increasing the autonomy of UAS's is widening the range of tasks which can be carried out without, or with minimal, external help. READ MORE

7. 5. Navigation Functionalities for an Autonomous UAV Helicopter

   Author : Gianpaolo Conte; Patrick Doherty; Marconi Lorenzo; Linköpings universitet; []
   Keywords : Unmanned Aerial Vehicle; Control System; Path Following; Path Planning; Sensor Fusion; Vision Based Landing; Kalman Filter; Real-Time; TECHNOLOGY; TEKNIKVETENSKAP;

   Abstract : This thesis was written during the WITAS UAV Project where one of the goals has been the development of a software/hardware architecture for an unmanned autonomous helicopter, in addition to autonomous functionalities required for complex mission scenarios. The algorithms developed here have been tested on an unmanned helicopter platform developed by Yamaha Motor Company called the RMAX. READ MORE
