摘要：

根据重复使用运载器末端能量管理段的初始位置，采用蛇形机动原理规划横侧向参考轨迹，即消除初始
位置误差并使轨迹终点进入自动着陆窗口. 将初始位置误差分解为横向和纵向误差，分阶段予以消除. 在消除横向
误差阶段，提出消除横向误差同时兼顾减小纵向误差的轨迹形式. 在消除纵向误差阶段，根据误差大小采用相应轨
迹模态形式予以消除. 仿真结果显示，该算法具有快速、准确、鲁棒性强的特点. 作为TAEM段三维制导轨迹生成
的核心部分，横侧向参考轨迹算法为应急情况下的在线轨迹生成提供了基础算法.

Abstract:

Abstract: According to the initial position of reusable launch vehicles (RLV) in terminal area energy management (TAEM), the lateral reference trajectory is planned to erase the initial position errors using the SNAKE algorithm. The course of lateral reference trajectory planning can be divided into two phases: erasing the lateral position error and erasing the longitudinal error. In the former phase, the longitudinal error is decreased. For erasing the longitudinal error, we propose to erase the error by proper trajectory mode according to its size. The lateral trajectory planning algorithm provides a kernel algorithm for 3-D TAEM trajectory generation which is a basis of onboard trajectory generation of RLVs’ TAEM guidance.

Key words: reusable launch vehicle, terminal area energy management, lateral trajectory planning, trajectory mode
