Distributed Attitude Coordinated Control for Spacecraft Formation Flying with Unknown Disturbances Via Sliding Mode Control

This paper addresses the attitude synchronization control problem of multi-spacecraft systems when formation spacecraft are affected by unknown disturbances and uncertainties. A robust attitude coordination control strategy via sliding mode control is proposed to enhance the robustness of formation systems to disturbances. The attitude consensus is able to be realized under the developed controller. Moreover, the asymptotic stability of the closed-loop system is proved through Lyapunov stability analysis. Finally, simulation results are illustrated to demonstrate the effectiveness of the designed control method.
