Distributed Formation Control for Multiple Spacecraft with Event-triggered Communication

This paper discusses a distributed formation control for multiple spacecraft system under the directed communication topology. By considering only a portion of the follower access to the leader's information, a distributed estimator and an adaptive control law are proposed to account for parametric uncertainties and the leader's constant velocity. To reduce the communication cost, the event-triggered strategy is provided. Then, it is proved through Lyapunov analyses that the multiple spacecraft can achieve the expected configuration and all follower can track the dynamic leader. Meanwhile, the Zeno behavior can avoid. Finally, the numerical simulation is carried out to verify the theoretical results.
