拦截机动目标的分布式协同围捕制导方法

In this paper, the problem of distributed cooperative encirclement hunting guidance for multiple aircrafts intercepting a maneuvering target in the multi-leader multi-follower mode is studied. Based on the biological mechanism of wolves' cooperative encirclement hunting of large maneuvering prey, three strategies for the cooperative guidance architecture in the leader-follower mode, distributed communication and state estimation, and multi-channel and multi-directional cooperative encirclement hunting guidance Law are abstracted mathematically. Firstly, for the leader-follower cooperative guidance ar-chitecture, a cooperative encirclement hunting scheme in the multi-leader multi-follower mode is proposed. Secondly, for multi-leader aircrafts, a cooperative anti-orbit interception guidance law with target?s uncertain maneuver compensation is developed to provide a favorable reference trajectory for the follower aircrafts. For multiple followers, a distributed state observer is used to estimate the convex combination of the state trajectories of multiple leaders. A time-varying encirclement hunting line of line-of-sight formation tracking guidance law is designed by using local information, and a dynamic compensation system is introduced to solve the input saturation problem. Then, the stability analysis of the closed-loop system and the feasibility analysis of the cooperative guidance system are conducted. Finally, the theoretical results are verified by numerical simulation. The simulation results show that it is appropriate for multiple aircrafts to form a certain encirclement hunting configuration on both sides of the target escape direction. That is, there exist several proper terminal guidance interception positions for aircrafts, which can improve maneuvering target interception efficiency.
