摘　　要：弹道式飞行器飞行过程中许多不可预料的干扰对其制导系统的“鲁棒性”提出了很高的要求。本文在分析了传统的摄动制导方案(即δ制导方案)在实际飞行中的抗干扰能力差等缺点的基础上,根据弹道式飞行器在空间的运动特性提出了一种基于虚拟再入点状态参数控制泛函的新型摄动制导方案。通过系统的理论和方法对该新型摄动制导方案的合理性、有效性和优越性进行了科学、系统地研究分析,在建立的制导模型基础上进行了严格地科学仿真计算并对该制导方案的部分优越性进行了验证和揭示。High requirements of “robustness” for the guidance system of the ballistic vehicle are needed when the vehicle encountering many unpredictable disturbances in flight. On the basis of analysis of the flaw and the lack of the general perturbation guidance scheme (δ guidance scheme), a new virtual reentry point parameter perturbation explicit guidance scheme is put forward for the first time based on the characteristics of ballistic flight. The rationality, validity and the advantage of the new guidance scheme are systemically studied by the scientific theory and method. Precise scientific calculations have been carried out based on the new guidance model and some merits of it are validated by the simulations.
