This paper presents a planetary elliptic displaced orbit (PEDO) for a solar sail with reflectivity control devices (RCDs). The problem of multiple solar sail formation flying in which the leader follows the PEDO is investigated. The trajectory of the leader is not affected by that of the followers, whereas each follower needs to know the state information of the leader to achieve formation configuration. An undirected and connected graph is used to describe the communication topology among the followers, and an event-triggered coordinated control algorithm is proposed. With this algorithm, each follower does not need to maintain continuous communication with other followers, reducing communication burden. Additionally, the existence of Zeno behavior is excluded by theoretical analysis. Finally, numerical simulations are performed to verify the effectiveness of the proposed algorithm.

本文提出了一种带有反射率控制装置（RCD）的太阳帆行星椭圆位移轨道（PEDO）。研究了领导跟随PEDO的多次太阳帆编队飞行问题。领导者的轨迹不受追随者的轨迹的影响，而每个跟随者都需要知道领导者的状态信息以实现编队配置。利用无向连通图描述随从之间的通信拓扑，并提出了一种事件触发的协调控制算法。使用此算法，每个关注者都无需与其他关注者保持连续的通信，从而减轻了通信负担。另外，理论分析排除了芝诺行为的存在。最后，
