Due to the non-Euclidean property of the attitude configuration space, the attitude consensus is more challenging to achieve under the sampled-data setting. An event-triggered attitude protocol and event-triggered condition are proposed based on the axis-angle attitude representation. The fixed-time attitude consensus is reached if the initial attitudes lie in local regions on the attitude configuration space and Zeno-behavior can be avoided. The theoretical results reveal that the settling time is related to the inter-event interval and the algebraic connectivity of the topology graph. We further consider the consensus protocol under a jointly connected graph. The settling time estimation is also obtained in this case, which is dependent on the switching instants. Numerical simulations are conducted to verify the validity of the theoretical results finally.en0018-92862022841384145IEEETechnikJournal Article10.1109/TAC.2021.3108514Other
