Decomposition and Control of Multiple Spacecraft Formation Flying
We propose a novel control framework for the formation flying of multiple spacecraft. With the passive decomposition, group dynamics of the multiple spacecraft is decomposed into two decoupled dynamics: the shape system representing the internal group formation shape (formation, in short), and the locked system describing the total group maneuver (maneuver, in short). Then, some desired formati...
متن کاملRecon gurable Control for the Formation Flying of Multiple Spacecraft
Several results on the recon gurable control architecture for the formation ying of multiple spacecraft are presented. In this direction, simple control laws are combined with logic-based switching to propose a hybrid control architecture for leader reassignment, leader-following capturing, and dealing with control saturations.
متن کاملGuidance and Control of Formation Flying Spacecraft
A key element of NASA’s future space exploration is high precision formation flying (FF) for space interferometry. Precision FF has never been attempted before and poses new and significant challenges to the underlying control system. While the guidance and control (G&C) methodologies of single spacecraft for traditional planetary flyby and orbiter missions are well-understood, the G&C of FF mi...
متن کاملEfficient Control of Formation Flying Spacecraft
Several upcoming European and American space missions will be operated using a number of spacecraft flying in formation. The associated scientific challenges are demanding, both with respect to the construction of the spacecraft as well as to the mission design. For instance, energy efficient trajectories and corresponding control laws that enable precision formation flying over long periods of...
متن کاملModel Predictive Control for Formation Flying Spacecraft
Formation flying is an enabling technology for many future space missions. This thesis addresses some of the key dynamics and control issues expected in future missions by pursuing two areas of advancement: extensions of relative linear dynamics models and assessment and mitigation of sensor noise effects on control systems. Relative dynamics models play an important role in finding drift-free ...
