基于虚拟领弹-从弹的集群分布式协同制导技术研究

On virtual leader-follower-based distributed cooperative swarm guidance strategy

本文讨论了多导弹集群分布式协同制导的问题并设计了一种基于虚拟领弹-从弹架构的制导律用于满足攻击时间约束的要求.该分布式协同制导律是一种由基础制导指令和攻击时间误差反馈项组成的复合制导律.对于仅考虑终端攻击时间约束的场景,基础制导律为传统的纯比例导引;若同时考虑终端落角和攻击时间约束,基础制导律为基于剩余飞行时间加权的最优落角约束制导律.通过理论分析,本文证明了所设计的分布式协同制导律能够使得所有导弹的攻击时间误差在目标命中时刻严格收敛于零.对于不考虑/考虑终端角度的场景进行仿真,验证了所提出制导律的有效性.

This paper investigates the problem of salvo attack guidance of multiple missiles and suggests a virtual leader-follower-based distributed cooperative guidance law to address this problem. The proposed guidance law is composed of two different parts: a baseline guidance law and an impact-time error feedback term. For scenarios with only impact-time constraint, the baseline guidance law is chosen as the classical pure proportional navigation for target capture. When considering both impact angle and impact time constraints, the well-known time-to-go weighted optimal guidance is leveraged as the baseline guidance law. Theoretical analysis reveals that the impact-time discrepancy among all missiles converges to zero at the time of impact. Finally, numerical analysis is conducted to demonstrate the effectiveness of the proposed algorithm.
