Abstract

In order to intercept hypersonic vehicles in near-space, a head-pursuit cooperative guidance law is proposed in this paper. Firstly, interceptors are regarded as multi-agents, and the communication relationship between them is represented by graph theory. Based on the time consistency theory of multi-agent system and sliding mode theory, a guidance law is designed along line-of-sight (LOS) to ensure the time cooperation of interceptors. Secondly, considering the requirement of the head-pursuit theory to the lead angle, a finite-time guidance law is designed perpendicular to LOS to ensure that each interceptor can complete head-pursuit interception. For the purpose of improving the intercept precision, extended state observers are used to estimate the system disturbances. The correctness of the guidance law is analyzed by Lyapunov stability theory. Finally, numerical simulations are presented and the results further verify the correctness of the guidance law.
近空间高超声速拦截弹头追协同制导律研究
为了在近空间拦截高超声速飞行器,提出了一种头追协同制导律。首先,将拦截器视为多智能体,用图论表示它们之间的通信关系;基于多智能体系统的时间一致性理论和滑模理论,设计了一种沿视距(LOS)方向的制导律,以保证拦截弹的时间协同。其次,考虑到头追理论对前导角的要求,设计了垂直于视距的有限时间制导律,保证每个拦截弹都能完成头追拦截;为了提高拦截精度,采用扩展状态观测器对系统扰动进行估计。利用李亚普诺夫稳定性理论分析了制导律的正确性。最后进行了数值仿真,结果进一步验证了制导律的正确性。
