Leader-Follower Consensus Control For Multi-Spacecraft With The Attitude Observers On SO(3)

Abstract

The issue of leader-follower consensus control for the multi-spacecraft structure on SO(3) has been studied in this article. An attitude observer has been utilized to reckon the attitude information of the reference spacecraft, which is not available for all followers. A new attitude error has been proposed. With the observer and the proposed attitude error, sliding mode control has been exploited to investigate a distributed control protocol for the leader-follower systems. Both the availability of the observer and the feasibility of the control approach are rigorously mathematically proven. Finally, a simulation outcomes confirm the superiority and validity of the protocols.
