导引控制延时对追踪捕获性能影响的研究

在深入分析国内外有关追踪捕获性能研究成果的基础上，就导引控制延时对捕获能力影响的新内容进行了专门研究。在对理想的、无延时假设下获得的理论成果进行系统分析与仿真研究的基础上，采用仿真计算的方法，从捕获概率和追踪过程两个方面，对导引控制延时与导引捕获性能的关系进行了系统研究与分析，获得了关于控制延时对追踪捕获能力和具体追踪过程影响的研究成果。指出如果控制延迟不大于0．02s．对捕获性能没有明显影响。可为导引内回路设计提供参考。

Study on Time-Delay Effect on Capture Capability of Pursuit-Control

Based on the profound analysis on conventional laws in some related fields, a new study of time-delay-control effect on the capture c apability of PN law is innovatively proposed, and a new important conclusion is obtained. Firstly, the no-time-lag theoretical results of PPN are validated by simulation. The results demonstrates the correctness of theorem and the validi ty of the system modeling and simulation method. Then, the effects on capture pr o bability and pursuit process are studied by simulations at different control lag time, some results on pursuit control time-lag are drawn from the simulatio n of two different aspects. The capture capability can almost be unchanged if th e control-delay is not more than 0.02 s. It is important for the inner-loop de sign of the pursuit-control system.
