| 摘 要： | 从六自由度动力学仿真结果入手，分析了翼伞系统飞行的基本特性，在此基础上进一步简化了模型。对于分段规划法，详细介绍了其设计的思想和各阶段的特点，并根据不同的情况提出了一整套的归航方案。对于最优控制法，介绍了其建模过程，在求解中采用了单位为1的量和等数量级的预处理方法，以提高计算精度，也便于加权因子的选择。通过算例验证了两种方法的可行性，并通过对比说明了各自的特点，为工程实际的运用提供了一定的参考。

| Abstract: | Firstly, based on six degree-of-freedom kinetic modeling and simulating, basic flight characters of parafoil system and predigest the model are analyzed. Then, the idea of multiphase trajectory programming and features in each phase are introduced. And a set project for different conditions is brought forward. The process of mod also introduced. Normalization and equal scale, these two pretreatment eling meth for optimal of homing control is ods improve precision of calculation, and facile choice of weighting factors. At last, a sample testifies the feasibility of the two methods and shows the characters for each. |
