摘要:

针对仅有相对角度信息的空间交会问题,进行了基于可观测性分析的单测角相对导航与闭环制导技术研究。首先,建立了系统滤波模型,并从新视角对滤波系统进行了可观测性分析,得到了系统可观测的充分条件。然后,结合多脉冲滑移安全制导策略分析了单测角相对导航与制导的耦合关系,得到了耦合关系的数学表达,并利用耦合关系设计了相对导航与闭环制导方案。最后,通过Monte Carlo打靶仿真验证了该方案的有效性,并分析了不同传感器误差与初始状态误差水平下的导航与制导精度。

Abstract:

Aimed at the problem of space rendezvous using angles-only measurements, relative navigation integrated with closed-loop guidance is developed based on observability analysis. Firstly, the systemic filtering model is established, based on which the observability is investigated from a novel prospect and the observable condition is obtained. Then, integrated with multi-pulse sliding safe guidance strategy, the coupling relationship between angles-only relative navigation and guidance is analyzed and the mathematical expressions are obtained. After that, the integrated scheme of relative navigation and closed-loop guidance is designed by using the coupling expresses. Finally, Monte Carlo simulations are conducted to validate the approach and the performance of navigation and guidance with different accuracies of sensor and initial relative states is analyzed.

Key words: observability analysis, Monte Carlo method, angles-only, navigation, guidance, autonomous rendezvous
