Analysis of an Application where the Unscented Kalman Filter is not Appropriate

Anderson, Abby (2009-09-15)

In this work a spin stabilized rocket with a ring of lateral pulse jets for attitude correction and fins that open early in flight is simulated. The rocket is simulated with five different sensor packages: rate gyros ...

Analysis of Simulated Performance of Integrated Vector Tracking and Navigation Loops for GPS

Hamm, Christopher (2005-12-15)

An alternative GPS signal tracking method that uses an extended Kalman-Bucy filter in place of traditional independent, parallel tracking loops is presented in this thesis. Furthermore, this method is extended into a ...

Applications of Multi-channel Filter Banks to Textured Image Segmentation

Davis, Craig (2006-08-15)

Multi-channel filtering provides a robust solution to the texture discrimination/ segmentation problem for digital image processing. Specifically, the use of the Gabor filter for channel characterization is explored. Tag ...

Characterization and Dynamic Analysis of Damping Effects in Composite Materials for High-Speed Flywheel Applications

Moreira, Alfonso (2007-05-15)

The directional mechanical properties of carbon fiber reinforced composite materials make them suitable for components of flywheel energy storage systems. Particularly the hub-rim interface is a component where fiber ...

Design, Testing, and Simulation of a Low-Cost, Light-Weight, Low-g IMU for the Navigation of an Indoor Blimp

Anderson, Abby (2006-05-15)

In this thesis we develop an IMU for the purpose of navigating an autonomous indoor blimp. Due to the unique system properties of an indoor blimp, the developed IMU is light-weight and is capable of measuring slow rotational ...

GPS and Inertial Sensor Enhancements for Vision-based Highway Lane Tracking

Clanton, Joshua (2006-08-15)

For the past decade much research in the Intelligent Transportation Systems (ITS) community has been devoted to the topic of lane departure warning (LDW). A significant portion of highway fatalities each year are attributed ...

Modeling Inertial Measurement Units and Anlyzing the Effect of Their Errors in Navigation Applications

Flenniken, Warren (2005-12-15)

In this thesis, a simple model that statistically represents an Inertial Measurement Unit (IMU) output has been studied. This model is then expanded to produce a model that incorporates terms that account for errors ...

Nonlinear Systems Control Using a Subset Stabilization Approach

Simmons, Adam (2006-05-15)

Numerous problems in nonlinear control systems are difficult or impossible to solve with commonly proposed methods of design. For such systems, we propose a two-loop control strategy that we call the subset stabilization ...

Particle Swarm Optimization Applied to the Design of a Nonlinear Control

Broderick, David (2006-05-15)

A method of searching for a tuning of an input to state linearizing controller is presented. The problem of ?nding the appropriate weights of the control law’s terms is treated as an optimization problem. Given the highly ...

Registration and Tracking of Objects with Computer Vision for Autonomous Vehicles

Nevin, Andrew (2009-04-15)

For this research, an autonomous leader-follower vehicle caravan is being designed using computer vision. The focus of this research is to investigate computer vision methods of identifying objects detected by the leader ...

A Technique for the Measurement of Relative Velocity between Parallel Plate Electrodes in Micromachined Structures

Dean, Robert (2006-05-15)

Numerous applications exist for microstructures that contain two parallel oriented electrodes that experience relative motion. It is often desirable to measure the relative velocity between the two electrodes and then ...
