翼伞系统归航的最优控制

Optimal Control of Parafoil System Homing

阐述了翼伞系统归航轨迹最优控制的建模。在求解过程中采用无量纲化和等数量级的预处理方法 ,提高了计算精度 ,使结果更直观 ,也便于选择加权因子。通过选择合适的加权因子 ,将有终端约束的单目标优化和无终端约束的多目标优化用同一程序求解。分析和总结了在不同初始条件下翼伞系统归航最优控制的特点 。

In this paper,the modeling of optimal control in parafoil homing trajectory is discussed in detail. Two pretreatment methods, normalization and equal scale, are used to improve calculating precision so as to make results comprehensible and weighting factors be easily chosen. If weighting factors are given properly, mono-object optimization with terminal restrictions and multi-object optimization without terminal restrictions could be solved with the same program. The features of optimal control under different initial conditions are analyzed and summarized in the end.
