Inertial Navigation System, Michael Calabrese Jr., David Engblom, Aaron Fleckenstein

Honors Theses

Accelerometer-based inertial navigation systems present an inexpensive alternative to gyroscope and global positioning navigation systems. An array of accelerometers comprises the basic design of the inertial navigation system. The position of the device can be continuously updated based on the previous device location and measurements of the device acceleration. There are fewer moving parts in an accelerometer-based system than in a gyroscopic device, and it is free of the earth bound constraints of a global positioning system. The prototype wirelessly interfaces with a data-collection system, which processes the data and provides a graphical display of the trajectory traveled.

Design Of A Reconfigurable State Transition Algorithm For Fuzzy Automata, Paolo A. Tamayo

Masters Theses

An Ontological Controller, a type of supervisory controller used for complex industrial systems, is usually characterized by a large global state set. Monitoring the global state set of these systems is impractical when the desired goal path is chosen since the decision on the next state depends only on a small section of the total state space. The approach is to operate only in a small moving window of the large state transition path. The Hybrid Fuzzy-Boolean Finite State Machine (HFB-FSM) is part of the solution to implement this scheme. The HFB-FSM models the state graph along with plant data …

Segmentation Of Thermal Images For Non-Destructive Applications, Solange Yohali

Masters Theses

Infrared Thermogarphy (IR) is used in this project to detect subsurface conditions in concrete specimen for nondestructive testing and evaluations. This thesis goal is to bridge the gap between Infrared Testing and image analysis by developing an algorithm based on the region growing approach to segment the images and identify the voids without human interference or prior knowledge of the conditions. The segmentation algorithm starts with seed points as the hottest pixels in the image, and then regions are grown based on a neighborhood comparison criterion. The algorithm was tested on images collected from concrete specimen containing various man-made defects …

Tilt-Rotor Aircraft Flight Control Design With Pid, H2, H∞ And Μ Synthesis Approach, Yinyang Zhai

Masters Theses

The main objective of this project is to design optimal controllers for Hover and Cruise Dynamic Systems of XV-15 Tilt Rotor Aircraft. The design criterion is to make system Robust in sense of both Stability and Performance. μ synthesis is applied to system uncertainty; this method is less conservative as compared to the worst-case H_∞ synthesis. The power of P∆K architecture is to represent uncertainties and system interconnections in μ synthesis. For comparison, the classical control techniques, such as Root Locus Algorithm, PID controller design with ITAE Performance Index, and Pole Placement Approach are also investigated. For application of …
