1	Autonomous landing system for a UAV / Autonomous landing system for a Unmanned Aerial Vehicle Lizarraga, Mariano I. 03 1900 (has links) Approved for public release, distribution is unlimited / This thesis is part of an ongoing research conducted at the Naval Postgraduate School to achieve the autonomous shipboard landing of Unmanned Aerial Vehicles (UAV). Two main problems are addressed in this thesis. The first is to establish communication between the UAV's ground station and the Autonomous Landing Flight Control Computer effectively. The second addresses the design and implementation of an autonomous landing controller using classical control techniques. Device drivers for the sensors and the communications protocol were developed in ANSI C. The overall system was implemented in a PC104 computer running a real-time operating system developed by The Mathworks, Inc. Computer and hardware in the loop (HIL) simulation, as well as ground test results show the feasibility of the algorithm proposed here. Flight tests are scheduled to be performed in the near future. / Lieutenant Junior Grade, Mexican Navy Drone aircraft Control systems Electrical engineering Navigation Flight Silver fox Unmanned aerial vehicles UAV Silver Fox Autonomous navigation Shipboard landing UAV control system Real time workshop xPC target Piccolo
