Abstract: The coupling of satellite attitude motion and antenna flexible vibration has more influence on the antenna slewing, which is examined in this paper. First of all, the flexible boom is simplified as an equivalent cantilever beam structure, and the multibody coupling dynamics is established based on the Lagrange equation. Then the impacts of antenna slewing motion on attitude stabilization and flexible vibration are analyzed according to the coupling dynamic model. Based on the analysis results, the command preprocessing algorithm is introduced to plan the antenna slewing process. Finally, simulation analysis is performed for the antenna slewing motion. The simulation results show that the command preprocessing algorithm can effectively reduce the influence of the slewing on attitude stabilization and flexible vibration.

Key words: intersatellite link antenna, flexible multibody satellite, slewing movement, command preprocessing
