Three-Dimensional Distributed Cooperative Guidance via Motion Camouflage Theory Against Hypersonic Vehicles With Speed Advantages

To quickly achieve simultaneous or domain capture of the hypersonic vehicles whose flying can execute various kinds of maneuver types and speed has advantages, this article explores an appointed-time-consensus-based 3-D distributed cooperative guidance scheme using multiple interceptors with relatively low speed for effectively. The leader-follower communication topology structure is first introduced by targeting the high-speed and high-maneuverability targets, in which the leader with a seeker detects target information and communicates with followers who are seekerless. Then, the appointed time consensus distributed cooperative algorithm is ultimately derived based on the specified-time convergence theory, motion camouflage (MC) technique, and fast nonsingular terminal sliding mode control. The theory proves the proposed cooperative guidance scheme is robust and can achieve convergence at a preset time. Meanwhile, the leader carrying the seeker satisfies the MC constraint and can successfully realize the role of camouflage and hide the detection information. To this end, simulations illustrate the distributed cooperative guidance strategy's effectiveness, superiority, and robustness.
