本文的目的是研究多航天器连续通信的姿态协作控制。提出一种分散的状态无关事件触发控制策略，通过引入自触发机制来降低控制更新频率，进一步实现连续通信。每个航天器独立传输数据，不需要整个系统同时通信。本地预测和自触发机制避免了对触发条件的持续监控。,本研究适用于小欧拉角条件。,基于事件触发通信的控制策略可以为节省通信资源提供潜在的解决方案。,本研究采用事件和自触发策略来实现多航天器系统的通信。
The purpose of this paper is to investigate the attitude cooperation control of multi-spacecraft with in-continuous communication.,A decentralized state-irrelevant event-triggered control policy is proposed to reduce control updating frequency and further achieve in-continuous communication by introducing a self-triggered mechanism.,Each spacecraft transmits data independently, without the requirement for the whole system to communicate simultaneously. The local predictions and self-triggered mechanism avoid continuous monitoring of the triggering condition.,This investigation is suitable for small Euler angle conditions.,The control policy based on event-triggered communication can provide potential solutions for saving communication resources.,This investigation uses event- and self-triggered policy to achieve in-communication for the multi-spacecraft system.
