摘要:

基于增强型比例导引律和分布式网络同步理论，设计了一类攻击机动目标的多导弹系统分布式协同制导律。该制导律由各导弹本地制导律和分布式协同导引策略两部分组成：本地制导律为增强型比例导引律，进一步利用代数图论和非线性系统一致性理论，得到基于邻接个体信息交互的分布式协同制导律，实现多导弹对目标的同时协同攻击;该分布式协同制导律仅需视距内各相邻导弹间互相传输各自的状态信息，算法具有较低的通信代价和较好的可扩展性。最后给出了相关数值仿真算例，仿真结果验证了算法的有效性。

Abstract:

A set of distributed cooperative guidance law of multimissile systems for maneuvering target attacking is developed on the basis of the augmented proportional guidance and synchronization theory of distributed networks. The proposed guidance law is based on local guidance law combined with distributed cooperative guidance strategy. The local guidance law is derived from augmented proportional guidance law. Furthermore, the distributed cooperative guidance law which could steer all missiles to intercept the maneuvering target simultaneously is synthesized via the algebraic graph theory and consensus principles of nonlinear systems. The designed cooperative guidance law relies on only local interaction with neighboring states within line-of-sight range and exhibits low communication cost as well as good scalability. Finally, related numerical simulations are performed to verify the effectiveness of the proposed guidance law.
