1. 1. Navigation Functionalities for an Autonomous UAV Helicopter

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

   Sammanfattning : 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. LÄS MER

3. 2. On the utilization of Nonlinear MPC for Unmanned Aerial Vehicle Path Planning

   Författare :Björn Lindqvist; George Nikolakopoulos; Dimos Dimarogonas; Luleå tekniska universitet; []
   Nyckelord :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;

   Sammanfattning : 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.

4. 3. Fuzzy Control for an Unmanned Helicopter

   Författare :Bourhane Kadmiry; Dimiter Driankov; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Helicopter; Robust control; Fuzzy gain scheduling; Gradient descent method; Computer science; Datavetenskap;

   Sammanfattning : The overall objective of the Wallenberg Laboratory for Information Technology and Autonomous Systems (WITAS) at Linköping University is the development of an intelligent command and control system, containing vision sensors, which supports the operation of a unmanned air vehicle (UAV) in both semi- and full-autonomy modes. One of the UAV platforms of choice is the APID-MK3 unmanned helicopter, by Scandicraft Systems AB. LÄS MER
