Abstract: Conventional guidance laws often exhibit difficulty in approaching highly maneuverable targets and suffer from poor robustness. To address these limitations, this paper proposes a spatio-temporally consistent cooperative guidance method based on the fully actuated system (FAS) approach. First, a cooperative guidance model incorporating the approaching-time and approaching-angle constraints is established based on kinematic and dynamic equations, subsequently transformed into an FAS formulation. Second, leveraging the backstepping design, a sliding-mode-like guidance law and an event-triggered control barrier function optimization method are designed within the FAS framework. Specifically, cooperative guidance laws are developed for the line-of-sight (LOS) radial and normal directions, respectively, tailored for approaching a highly maneuverable target. The consistent convergence properties of the proposed method are rigorously proven theoretically. Finally, the effectiveness of the proposed guidance scheme is validated through comprehensive numerical simulations.
