A robust control approach for the formation flying of multiple spacecraft [PDF]
We present a disturbance rejection mechanism for the formation flying of multiple spacecraft based on a robust control approach in terms of an H ∞ control problem. The corresponding H ∞ control problem is then solved numerically using linear matrix inequalities.

Spacecraft Formation Flying in Eccentric Orbits
Formation flight of spacecraft in eccentric orbits is considered in this paper. Symmetry of the eccentric orbits is assumed in a relative formation orbit, and under this assumption, relations of initial conditions in formation flight are derived. Some characteristic orbits are obtained from these relations, such as an orbit where a deputy spacecraft ...

Optimal Reconfiguration of Formation Flying Spacecraft ---a Decentralized Approach [PDF]
This paper introduces a hierarchical, decentralized, and parallelizable method for dealing with optimization problems with many agents. It is theoretically based on a hierarchical optimization theorem that establishes the equivalence of two forms of the problem, and this idea is implemented using DMOC (Discrete Mechanics and Optimal Control).

Spacecraft formation flying using bifurcating potential fields [PDF]
The distributed control of spacecraft flying in formation has been shown to have advantages over conventional single spacecraft systems. These include scalability, flexibility and robustness to failures.

Solar sail formation flying for deep-space remote sensing [PDF]
In this paper we consider how 'near' term solar sails can be used in formation above the ecliptic plane to provide platforms for accurate and continuous remote sensing of the polar regions of the Earth.

ABSTRACT To confront extreme space environments, a combination of inorganic and organic coatings can provide a pathway for offering highly durable radiation resistance and anti‐friction simultaneously. Herein, a strong interfacial 3D hydrogen‐bonding network is designed to create robust hexagonal boron nitride (h‐BN) based polymer coatings with ...
