Cascade-Based Controlled Attitude Synchronization and Tracking of Spacecraft in Leader-Follower Formation

Abstract EN

We propose controllers for leader-follower attitude synchronization of spacecraft formations in the presence of disturbances, that is, the leader spacecraft is controlled to follow a given reference, while a follower spacecraft is controlled to synchronize its motion with the leader's.

In the ideal disturbance-free scenario, we show that synchronization takes place asymptotically.

Moreover, we show the property of uniform practical asymptotic stability which implies that the synchronization is robust to bounded disturbances.
