  1. 1. Model Predictive Control for Cooperative Rendezvous of Autonomous Unmanned Vehicles

    Author : Linnea Persson; Bo Wahlberg; Jonathan How; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; 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

  2. 2. 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

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

    Author : Björn Lindqvist; George Nikolakopoulos; Dimos Dimarogonas; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; 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.
