Satellite formation cooperative control based on Lagrange Planetary Equations

For low-Earth orbiting satellite formations effects of other bodies can be disregarded; individual trajectories are Keplerian ellipses if no controls are applied. When the controls are acting the orbits change according to Lagrange Planetary Equations. Formulate the consensus problem appropriate for a chosen satellite formation and show cooperative stability. This would allow completely autonomous station keeping, excluding the need for ground stations.
