飞行器轨迹优化数值方法综述

A Survey of Numerical Methods for Trajectory Optimization of Spacecraft

自上世纪后期,出现了多种飞行器轨迹优化方法,但较全面地对各种方法进行综合研究的文献非常有限且近期未见公开发表。通过对近百篇相关文献的调研,从各种角度对轨迹优化方法分类,并总结了常见方法的特点和应用情况。同时还概述了一些很有应用前景的如伪谱法,快速探索随机树法和滚动时域优化等新方法的特点和进一步需要解决的问题。本文不对优化算法作过多的讨论,而是注重各种优化方法,这些方法的不同体现在对连续最优控制问题的转换、离散化方法等方面。希望本文的工作可为未来轨迹优化领域的研究和技术发展提供一个良好的基础。

From the later period of the last century,diverse methods for trajectory optimization appeared.Otherwise only a few of papers about the survey of this field were presented and that not being published recently.By the investigation of a bibliography of approximately 100 papers,varied trajectory optimization methods are categorized from several points of view and their characteristics and applications are presented.And then some promising new methods such as Pseudospectral method,Rapidly-exploring random tree...
