Dynamic Modeling and Composite Attitude Cooperative Control for Dumbbell-Shaped Spacecraft

This study proposes a composite attitude coordination control approach to enhance attitude stability and suppress vibrations during the attitude maneuver of a dumbbell-shaped spacecraft (DSS). First, a dynamic model is formulated that accounts for actuator faults and external disturbances while enabling distributed attitude coordination control. Then, leveraging graph and consensus theories, an attitude coordination consistency algorithm is developed. A virtual leader is designed using model predictive control. Force synthesis techniques are integrated with attitude coordination methods featuring a virtual leader. A composite attitude coordination control strategy is developed in this way to ensure both attitude stability and vibration suppression. The system’s stability is analyzed using the Lyapunov theory. Finally, simulations demonstrate the effectiveness and practical feasibility of the proposed approach.
