This article investigates the decentralized coordinated control problem for formation flying spacecraft associated with coupled attitude and translational dynamics by probing into local information exchange among spacecraft. A six degree-of-freedom coupled model is established by employing the unified Euler–Lagrange formulations of attitude dynamics and translational dynamics. With the novel use of adaptive control, a six degree-of-freedom continuous robust coordinated controller is proposed in the presence of parametric uncertainty and time-varying disturbances with unknown bounds. Furthermore, it is extended to the case where both of switching topologies and non-constant communication delays exist. The six degree-of-freedom coordinated controller can guarantee formation spacecraft follow a time-varying reference trajectory while aligning their attitudes and keeping some special formation configuration. Numerical simulations demonstrate the effectiveness of the proposed control scheme.
