Abstract
This paper is devoted to solving the multi-spacecraft attitude synchronization problem via performance adjustable event-triggered control in the presence of external disturbances and model uncertainties. In the proposed control policy, the inter-spacecraft information interaction is determined by an event-triggered sampling mechanism, and the influences of external disturbances and model uncertainties are counteracted by an adaptive estimation. This sampling method does not only reduce communication resource consumption but also provides a trade-off between resource savings and synchronization accuracy. Moreover, the corresponding performance-adjustable triggering function can achieve Zeno-free triggering. According to the comparison of some numerical simulation results, this paper shows that the provided control policy is effective and superior.
