一种用于小推力弹道优化的高保真度直接转录方法

Towards a High Fidelity Direct Transcription Method for Optimisation of Low-Thrust Trajectories

Chit Hong Yam, Dario Izzo, Francesco Biscani

摘要:

我们建立在一些新的想法,在直接转录方法开发的先进概念团队介绍两个改进的西姆斯-弗拉纳根转录低推力轨迹。所得到的新算法能够产生一个实际的航天器动力学和自适应的段持续时间在线提高最终轨迹的最优性占的操作轨迹。

英文摘要:

We build upon some new ideas in direct transcription methods developed within the Advanced Concepts Team to introduce two improvements to the Sims-Flanagan transcription for low-thrust trajectories. The obtained new algorithm is able to produce an operational trajectory accounting for the real spacecraft dynamics and adapting the segment duration on-line improving the final trajectory optimality.
