Event- and self-triggered control of attitude coordination to multi-spacecraft system

Purpose The purpose of this paper is to investigate the attitude cooperation control of multi-spacecraft with in-continuous communication. Design/methodology/approach 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. Findings 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. Research limitations/implications This investigation is suitable for small Euler angle conditions. Practical implications The control policy based on event-triggered communication can provide potential solutions for saving communication resources. Originality/value This investigation uses event- and self-triggered policy to achieve in-communication for the multi-spacecraft system.
