Event-triggered group attitude coordinated control of multi-spacecraft system with directed topology is studied. The event-triggered strategy ensures that the system communicate at discrete time instants, thus the communication burden is reduced. Based on assumptions on the topology, the Laplacian matrix of the multi-spacecraft system is a block upper triangular matrix, and the nonnegative eigenvalues of it are positive integers, which can simplify the analysis process. With variable substitution and the Laplacian matrix decomposition, the problem is turned into a second-order group consensus problem, and then turned into a stability problem of a linear system. By properly chosen parameters, the system matrix of the linear system is Hurwitz. With centralized event-triggered mechanism, the control input proposed can lead the system to group attitude coordination, and Zeno behavior is avoided. Simulation results show that the variable substitution method utilized and controller designed in this paper are effective.
