Abstract: In the task of satellite cooperative formation, the satellite cooperative formation communication is limited by the communication bandwidth. To address the problem of cooperative formation of satellites under the condition of communication delay, by combining the constraints of limited bandwidth of satellite cooperative communication in cooperative formation, the satellite communication system is designed with a dual redundant communication information transmission mode mainly based on position and speed information. The controllability of the satellite cooperative system under the time delay conditions is analyzed by using the matrix method, and the influence of the dual redundant communication information transmission mode on the stability and convergence speed of the cooperative system is investigated. Finanly, based on the stable convergence of the communication delay system, a simulation example is designed to verify the effectiveness and stability of the proposed cooperative formation method under the time delay situation. The results show that the communication delay system constructed with the dual redundant communication information transmission mode based on position and speed converges stably, and the simulation results verify that the position of the satellites in cooperative formation converges rapidly and stably, and the speed quickly becomes consistent, forming a “straight line” formation.
