A new tracking control method for synchronization of spacecraft formation with switching topologies

This paper studies an attitude synchronization problem for spacecraft formation with switching interaction topologies. An adaptive control architecture which allows for parameter uncertainties and unknown external disturbances is established for the decentralized controllers design. This paper also shows that the attitude synchronization under dynamically changing interaction topologies can be achieved asymptotically if the union of the switching communication graphs is jointly connected in a finite time interval. Finally, some simulations indicate the capabilities of the proposed results.
