摘要

Aiming at the cooperative guidance problem with switching topologies, a three-dimensional prescribed-time cooperative guidance law ( PTCGL) is proposed to ensure the convergence of predetermined time packets in topology switching. Firstly, the 3D cooperative guidance model of the vehicle is established and the group framework with switching topologies is introduced, that is, the intra-group cooperation is guaranteed by the communications among group leaders and the inter-group cooperation can be achieved with directed communication. Then, in the case of topology switching of communication networks, combined with the pinning control and predetermined time theory, a pre scribed-time cooperative guidance law with switching topologies is proposed with time-scaling function and pinning group consensus based on M-matrix assumption. Furthermore, the prescribed-time stability of the guidance system with switching topologies is proved by Lyapunov theory and analyzed with dwell time. Finally, the numerical simulation results show that the prescribed-time convergence can be guaranteed with switching topologies and the proposed cooperative guidance scheme can achieve the cooperative mission effectively.
