Relative position coordinated control of spacecraft formation based on event triggered transmission

This paper considers the position coordination control of distributed spacecraft formation system with event triggered mechanism. Firstly, a modified event triggered mechanism for multiple spacecraft system is introduced to alleviate communication pressure. Then, based on this event triggered mechanism, an adaptive liner sliding model control algorithm is employed to achieve spacecraft formation position coordination with bounded external disturbance and uncertain mass. Finally, the numerical simulation is presented to demonstrate the performance of the proposed event triggered mechanism and control algorithm.
