Adaptive Control of Evolving Gossamer Structures
(Georgia Institute of Technology, 2006-08)
A solar sail is an example of a gossamer structure that is proposed as an propulsion
system for future space missions. Since it is a large scale flexible structure that requires a
long time for its deployment, active ...
Real-Time Vision-Based Relative Aircraft Navigation
(Georgia Institute of Technology, 2007-03)
This paper describes two vision-based techniques for the navigation of an aircraft relative
to an airborne target using only information from a single camera fixed to the aircraft. These
techniques are motivated by ...
A Compact Guidance, Navigation, and Control System for Unmanned Aerial Vehicles
(Georgia Institute of Technology, 2006-05)
The Flight Control System 20 (FCS20) is a compact, self-contained Guidance, Navigation,
and Control system that has recently been developed to enable advanced autonomous
behavior in a wide range of Unmanned Aerial Vehicles ...
Methods for Localization and Mapping Using Vision and Inertial Sensors
(Georgia Institute of Technology, 2008-08)
The problems of vision-based localization and mapping are currently highly active areas of research for
aerial systems. With a wealth of information available in each image, vision sensors allow vehicles to gather
data ...
Vision-Aided Inertial Navigation for Flight Control
(Georgia Institute of Technology, 2005-09)
Many onboard navigation systems use the Global Positioning System to bound the errors
that result from integrating inertial sensors over time. Global Positioning System information,
however, is not always accessible since ...
Vortex Model Based Adaptive Flight Control Using Synthetic Jets
(Georgia Institute of Technology, 2009-08)
A simple low-order model is derived for developing flight control laws for controlling
the longitudinal dynamics of an aircraft using synthetic jet type actuators. Bi-directional
changes in the pitching moment over a ...
Flight Results of Autonomous Fixed-Wing UAV Transitions to and from Stationary Hover
(Georgia Institute of Technology, 2006-08)
Fixed-wing unmanned aerial vehicles (UAVs) with the ability to hover have significant
potential for applications in urban or other constrained environments where the
combination of fast speed, endurance, and stable ...
Small Adaptive Flight Control Systems for UAVs Using FPGA/DSP Technology
(Georgia Institute of Technology, 2004-09)
Future small UAVs will require enhanced capabilities like seeing and avoiding obstacles,
tolerating unpredicted flight conditions, interfacing with payload sensors, tracking moving
targets, and cooperating with other ...
Nested Saturation with Guaranteed Real Poles
(Georgia Institute of Technology, 2003-06)
The global stabilization of asymptotically null-controllable
linear systems with bounded controls has
been studied extensively. An early contribution was
by Teel [6] who proposed a set of nested saturators to
globally ...
Development of an Autonomous Aerial Reconnaissance System at Georgia Tech
(Georgia Institute of Technology, 2003-07)
The Georgia Tech aerial robotics team has developed a system to compete in the International Aerial Robotics Competition, organized by the Association for Unmanned
Vehicle Systems, International. The team is a multi-disciplinary ...
