Magnetic Stabilization Of Nadir-Pointing Small Satellites, Chau Ton
Magnetic Stabilization Of Nadir-Pointing Small Satellites, Chau Ton
Master's Theses - Daytona Beach
Since magnetic control systems are relatively lightweight, require low power and are inexpensive, they are attractive for small, inexpensive satellites in low Earth orbits. In this thesis we present averaging-based feedback control laws that achieve three-axis stabilized nadir-pointing attitude. Two types of nonlinear feedback control laws are proposed: full-state feedback and passivity-based feedback. Full-state feedback uses the attitude and angular velocity measurements to regulate the spacecrafts dynamics. Passivity-based feedback uses the attitude measurement and doesn’t require the rate sensors. The control laws are tested using two magnetic field models: the tilted dipole model and the International Geomagnetic Reference Field (IGRF) …

A Sensitivity Analysis Of Scheduling Changes On Flight Training Resource Utilization Using Discrete Event Simulation, Melissa A. Findlay
Master's Theses - Daytona Beach
This study presented a scheduling model of the Flight Training Department at Embry Riddle Aeronautical University's Daytona Beach Campus built using ARENA 12.0. The purpose of the study was to determine if the Flight Training Department system was sensitive to changes in the resources available to students in Flight Training Device (FTD) course modules. Historical data from the Flight Training Department was used to build the model. As no significant difference was found between the actual real world system and the model for the number of active students and for the time it took students to complete the program, the …
