Dynamics and Control of Geostationary Satellite in GTO orbit During LAM Firing, M.Sc. Thesis Sharif University of Technology ; Meghdari, Ali (Supervisor) ; Nejat Pishkenari, Hossein (Supervisor)
Abstract
In this study, chapter 1 is dedicated to GEO satellites. In chapter 2, slosh dynamics of fluid and its governing dynamical equations are investigated due to the importance of this phenomena in geostationary transfer orbit. In chapter 3, dynamics of satellite orbit and satellite attitude are investigated and governing equations are derived by considering these effects: orbital noise (e.g. shape of earth, gravitation of sun and moon), moment noise (e.g. slosh dynamics of fuel and oxidizer, and liquid apogee motor misalignment). Following the third chapter, some simulations are carried out before the implementation of controllers. In chapter 4, a PID controller and a classical fuzzy controller...
