HYBRID CONSTRAINED FORMATION FLYING CONTROL OF MICRO-SATELLITES
Abstract This paper proposes a centralized solution to the problem of formation reconfiguration and keeping for fleets of satellites in the presence of persistent disturbances and under input-saturation and formation accuracy constraints. Relative position and attitude dynamics are considered.

Analysis of Linear and Nonlinear Relative Orbit Dynamics for Satellite Formation Flying [PDF]
Relative dynamic models of satellites which describe the relative motion between two satellites is fundamental for research on the formation flying. The accuracy of various linearized or nonlinear models of relative motion is analyzed and compared.

An observer based distributed controller for formation flying of satellites [PDF]
In this paper, a novel nonlinear observer and controller framework is suggested for achieving formation control of a cluster of satellites. Exploiting the skew symmetry in the satellite dynamics, a novel nonlinear observer which has roots in the super-twist sliding mode observer is proposed.

Network configuration analysis for formation flying satellites [PDF]
The performance of two networks to support autonomous multi-spacecraft formation flying systems is presented. Both systems are comprised of a ten-satellite formation, with one of the satellites designated as the central or "mother ship." All data is routed through the mother ship to the terrestrial network.

Satellite formation flying control by mass exchange [PDF]
Abstract Novel approach for formation flying relative motion control is proposed and studied. It is based on a mass exchange between satellites. A certain mass is separated from one satellite in a given direction with a given velocity. It impacts absolutely inelastically another satellite to impart a pulse.
