基于协调变量的多导弹协同制导

Multi-missile Cooperative Guidance Using Coordination Variables

根据多导弹协同攻击的特点和要求,提出了一种具有一定通用性的双层协同制导结构。该双层协同制导结构由底层导引控制和上层协调控制组成。其中底层导引控制由分散于各个导弹的本地制导律来实现,上层的协调控制可通过集中式或分散式的协调策略来实现。基于该协同制导结构并针对多导弹同时击中目标这一特定协同任务,给出了一种具体可行的多导弹协同制导律。该协同制导律把具有导引时间限制的制导律和基于协调变量的协调策略相结合,具有控制能量的次优性,结构简单且具有解析解形式。数字仿真算例验证了其良好的性能。

A two-level cooperative guidance architecture for multi-missile attack is proposed. The architecture is composed with local guidance for each missile on the lower level and a coordination strategy on the upper le-vel. It provides a general solution to some categories of multi-missile cooperative control problems. Based on the notion of decentralized guidance and centralized coordination,an application of the architecture to the salvo attack is investigated. A new practical cooperative guidance law,which could automatically guide missiles to hit the stationary target simultaneously,is devised. It is a combination of the guidance law with constraint on guidance time and the coordination strategy based on coordination variables. The cooperative guidance law is quite feasible because of its analytical form,and it is suboptimal in the sense of control energy. Numerical simulations are presented to demonstrate the effectiveness of the cooperative guidance law.
