Three-Dimensional Prescribed-Time Cooperative Guidance Law with Impact Angle Constraint
摘要
We propose three-dimensional cooperative guidance laws using leader-follower communication topology against stationary target. The guidance laws comprise a tangential component aligned with the line-of-sight (LOS) direction, as well as a normal component oriented perpendicular to the LOS direction. First, tangential guidance command for leader is designed to achieve predefined-time attack. Second, tangential guidance commands for followers are designed based on prescribed-time consensus control to achieve predefined-time synchronized strikes. Moreover, normal acceleration commands for both the leader and followers are designed based on the predefined-time global sliding mode faces to achieve impact angle constraints. Finally, simulations are given to validate the efficacy of the cooperative guidance laws.
