大气层外动能拦截器顺轨拦截制导律设计

A Guidance Law Design for Exoatmospheric Kinetic Interceptor

在分析中段拦截弹道导弹的优势和特点的基础上,提出顺轨拦截弹道导弹的方案。阐述顺轨拦截的概念,建立用于顺轨制导的弹道导弹和拦截器相对运动模型,基于二阶滑模控制理论设计二阶滑模非线性制导律。通过拦截器拦截弹道导弹的数字仿真验证了制导模型和制导律的正确性。

This paper analyzed the predominance and peculiarity of midcourse intercept. The concept of intercepting along track is brought forward on basis of the relative analysis. Firstly, the concept of intercepting along track is introduced. Secondly, relative motion model of ballistic missile and interceptor is established for along track guide. Finally, it designed second-order sliding mode nonlinear guidance law based on the second-order sliding mode control theory. Numerical simulation results verified the guidance model and the effectiveness of the guidance law.
