Abstract

Aiming at the positioning error of the aircraft, the error accumulation to a certain extent may lead to the failure of the mission. A track correction method based on oriented graph search was proposed, and the dynamic programming idea was applied to solve the path optimization problem. Firstly, the correction points in the flight space were preprocessed, and the planning of the correction points in the flight space was transformed into a graph theory problem. It effectively solves the problem that traditional methods did not adapt well to dynamic changes in flight space. And the problem of too high complexity in the calculation space. Using the dynamic programming idea to carry out the flight path planning for the flight space, the path-correction number optimal double-objective model is comprehensively established. Finally, the oriented graph and dynamic programming ideas were used to solve the problem, and the visual analysis of the aircraft track was realized. The simulation results show that the established path-corrected optimal double-objective model can calculate an optimal track with relatively small correction times and short length.

多约束双目标轨道规划问题研究
针对飞机的定位误差,误差累积到一定程度可能导致任务失败。提出了一种基于面向图搜索的航迹校正方法,并将动态规划思想应用于航迹优化问题的求解。首先对飞行空间中的校正点进行预处理,将飞行空间中校正点的规划问题转化为图论问题;有效地解决了传统方法不能很好地适应飞行空间动态变化的问题。以及计算空间复杂度过高的问题。利用动态规划思想对飞行空间进行航迹规划,全面建立航迹修正数最优双目标模型。最后,利用面向图和动态规划思想对问题进行了求解,实现了飞机航迹的可视化分析。仿真结果表明,所建立的路径修正最优双目标模型能够以较小的修正次数和较短的轨迹长度计算出最优轨迹。

期刊介绍: Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
