Abstract: In order to achieve coordinated work,the control system of spacecraft formation flying required a unified cooperative management.To enhance the cooperativity of attitude control for spacecraft formation flying,the synchronization control theory of networks was applied toattitude control of spacecraft formation flying.First,the modified rodrigues parameters(MRP) were adopted to describe the attitude dynamics of spacecraft;then,the nonlinear attitude cooperative control law was designed for spacecraft formation flying based on synchronization control algorithm of networks.Considering the differences of attitude change between the member spacecrafts,a hybrid control strategy was designed for spacecraft formation flying using hybrid control techniques.Simulation results validate the effectivity of the control method and the control law,and the hybrid control has better control characteristics compared to single feedback mechanism.
