Neural Network Augmented Kalman Filtering in the Presence of Unknown System Inputs
(Georgia Institute of Technology, 2006-08)
We present an approach for augmenting a linear, time-varying Kalman filter with an adaptive neural network (NN) for the state estimation of systems with linear process models acted upon by unknown inputs. The application ...
Approaches to Vision-Based Formation Control
(Georgia Institute of Technology, 2004-12)
This paper implements several methods for performing vision-based formation flight control of multiple aircraft in the presence of obstacles. No information is communicated between aircraft, and only passive 2-D ...
Fault tolerant nonliner adaptive flight control for the X-33
(Georgia Institute of Technology, 2009-07-14)
Trajectory optimization and guidance law development for NASP applications
(Georgia Institute of Technology, 1988)
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 ...
Adaptive Output Feedback Control of a Flexible Base Manipulator
(Georgia Institute of Technology, 2007-07)
This paper considers augmentation of an existing inertial damping mechanism by neural network-based adaptive control, for controlling a micromanipulator that is serially attached to a macromanipulator. The approach ...
Augmenting Adaptive Approach to Control of Flexible Systems
(Georgia Institute of Technology, 2004)
This paper describes an approach for augmenting a linear controller design with a neural-network-based adaptive element. The basic approach involves formulating an architecture for which the associated error equations have ...
Limited Authority Adaptive Flight Control for Reusable Launch Vehicles
(Georgia Institute of Technology, 2003-11)
In the application of adaptive flight control, significant issues arise due to limitations in the plant inputs, such as actuator displacement limits, actuator rate limits, linear input dynamics, and time delay. A method ...
Neural-Network Augmentation of Existing Linear Controllers
(Georgia Institute of Technology, 2005-01)
A method to augment existing linear controllers with a multilayer neural network is presented. The neural network is adapted online to ensure desired closed-loop response in the face of parametric plant uncertainty; ...
Adaptive Guidance and Control for Hypersonic Vehicles
(Georgia Institute of Technology, 2006-05)
Guidance and control technology is recognized as an important aspect of the military, civil, and commercial goal of reliable, low-cost, aircraft-type operations into space. Here, several guidance and control methods ...
