Cluster flight control for fractionated spacecraft on an elliptic orbit

Self-Organizing Control-Loop Recovery for Predictive Networked Formation Control of Fractionated Spacecraft

“…Distributed spacecraft systems with the described architecture were pioneered by the F6 program of DARPA [10,11] which was unfortunately cancelled before its in-orbit demonstration in 2013 [12]. Distributed modular spacecraft systems, due to their apparent benefits, have nevertheless seen further continuation in several other projects both with a theoretical [5,[13][14][15][16][17] and application focus [18,19]. Notable projects include the iBOSS initiative, that demonstrated the reconfiguration of the building blocks/nodes of a modular satellite with robotic manipulators on ground [20,21], the Innocube satellite mission, which is scheduled to launch in 2023 [22] and is expected to demonstrate the wireless harness of a modular satellite under space conditions [23] and finally the Yete-1 [5,24] and Yete-2 projects [25][26][27], which developed formation and attitude control for distributed spacecraft and constitute the precursor missions for the Tamariw project, which is scheduled to demonstrate these technologies with an in-orbit assembly of two Cubesats in 2025.…”

Formation Flying Along Low-Energy Lunar Transfer Trajectory Using Hamiltonian-Structure-Preserving Control

“…Named as a Hamiltonian-structurepreserving (HSP) controller, the controller was creatively designed by using the eigenstructure of linearized dynamics and was able to preserve the system's mathematical structure. Thereafter, the applicability of HSP control was widely studied in more trajectorykeeping issues [13][14][15] and formation-flying subjects [16][17][18]. However, in the previous works, the HSP control has only been employed in time-independent and time-periodic/quasi-periodic dynamics.…”
