Shape Remain for Near-Earth Radial Equilateral Three-craft Coulomb Force Formation

The problem of the equilateral three-craft Coulomb formation configuration control in the geosynchronous orbit (GEO) is studied in this paper. First, according to the three-craft Coulomb formation relative motion dynamics model, the Coulomb formation dynamics and the Debye effect are considered to establish the nonlinear relative motion dynamics model of equilateral three-craft Coulomb formation in the geosynchronous orbit. Then, based on the linearization dynamics model, the satellite’s sudden load changing is considered and an equilateral three-craft Coulomb formation controller is established by using DQN algorithm. Finally, simulation results show that the controller can make the formation achieve the desired configuration with favorable control performances.
