Adaptive Control Research of TwoCraft Coulomb Formation in Track Radial

In this paper, the adaptive control problem of the collinear threecraft coulomb formation configuration keeping at geostationary orbit is investigated. The nonlinear relative kinetic model of the collinear threecraft Coulomb formation in geosynchronous orbit is established, and the control strategy of only using the Coulomb force as the control force is studied to keep the radial static stability of the collinear threecraft Coulomb formation. Based on the nonlinear dynamic model, considering the unmodeled disturbance force at space environment, the adaptive control law is designed. Finally, the numerical simulation is carried out.
