Design and Optimization of PlaVi’s Attitude and Orbit Control System
2012 (English)Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
Abstract [en]

The Attitude and Orbit Control System of a spacecraft is crucial in the well-functioning of a space mission. Each one has its own singularities and requirements, so a full engineering process has to be done in order to meet those requirements considering the specific constraints of the mission. This work focuses on the study and development of two main AOCS components of the Planetary Vision (PlaVi) spacecraft. The first part consists on a complete analysis of the proposed reaction wheel system. Main perturbation forces are modeled in order to determine the load that these actuators will have to withstand. Different torque-distribution techniques and small tweaks are applied to optimize their performance. Lastly, a full characterization of the final capabilities and limitations of the system is presented. The second part shows the development of PlaVi’s Safe Mode, which uses a set of thrusters. It was divided into four different sub-modes that are discussed and simulated with the help of Simulink®. Finally, torque distribution among thrusters and its modulation is implemented as well.
