摘要

在飞行过程中,航天器需要在多个预定位置上调整姿态。遍历这些姿态的顺序是一个组合优化问题。本文通过分析姿态转换过程中的角动量变化来估算燃料成本。在此基础上,提出了一种同时面向燃料成本和机动时间的路径规划器优化算法。仿真结果验证了该方法的有效性。

Attitude maneuver path optimization for small scale spacescraft
During its flight, Spacecrafts need to maneuver its attitude across a number of predefined positions. The order to traverse these attitudes is a combinational optimization problem. In this article, fuel cost is estimated by analyzing the angular momentum change during attitude transitions. Based on this estimation, an optimization algorithm for both fuel-cost and maneuver-time oriented path planner is introduced. Simulation result demonstrated the effectiveness of proposed approach.
