摘要：
Group attitude coordinated control of multi-spacecraft on the basis of distributed event-triggered mechanism is investigated. The multi-spacecraft system contains several subgroups, and the information exchange among spacecraft is regarded as undirected topology. The attitude of spacecraft is described by Modified Rodrigues Parameters (MRP), an auxiliary variable with attitude and angular velocity is constructed, and distributed control input is designed. Under distributed event-triggered mechanism, triggering function is designed for every spacecraft. It is proved with algebraic graph theory and Lyapunov stability theory that multi-spacecraft can reach group attitude coordination asymptotically, and it is also proved that Zeno behavior will not occur in the system. The effectiveness of the control input proposed under distributed event-triggered mechanism is verified by simulation results. © 2021, Editorial Board of JBUAA. All right reserved.
