A hybrid proportional navigation based two-stage impact time control guidance law
文献摘要：
To improve applicability and adaptability of the im-pact time control guidance (ITCG) in practical engineering, a two-stage ITCG law with simple but effective structure is proposed based on the hybrid proportional navigation, namely, the pure-proportional-navigation and the retro-proportional-navigation. For the case with the impact time error less than zero, the first stage of the guided trajectory is driven by the retro-proportional-navigation and the second one is driven by the pure-proportional-navigation. When the impact time error is greater than zero, both of the stages are generated by the pure-proportional-navigation but using different navigation gains. It is demonstrated by two-and three-dimensional numerical simulations that the proposed guidance law at least has comparable results to existing propor-tional-navigation-based ITCG laws and is shown to be advant-ageous in certain circumstances in that the proposed guidance law alleviates its dependence on the time-to-go estimation, con-sumes less control energy, and adapts itself to more boundary conditions and constraints. The results of this research are ex-pected to be supplementary to the current research literature.
