摘　　要：子级垂直回收的一项关键技术是制导、导航与控制(Guidance Navigation and Control,GNC)技术。瞄准未来的组合体回收模式,结合现阶段发动机、着陆支架等环节的性能和特点,全面分析了返回过程中最关键的垂直着陆段对控制系统的需求和约束条件,研究了一种针对垂直着陆段的GNC技术,包含高精度导航算法、适应大推重比运载器快速下降模式着陆的凸优化在线轨迹规划与制导算法、适应大静不稳和晃动极零结构的参数优化设计以及基于自抗扰的高精度姿态控制算法。仿真结果表明,提出的技术可以满足设计需求。Vertical landing guidance navigation and control(GNC)is a key technology to realize launch vehicle reuse.Aiming at a developing strap-on reusable rocket,taking the characteristics of engines,landing legs into consideration,the requirements and constraints for control system during vertical return are analysed.A new method of guidance navigation and control is proposed,including high-precision navigation algorithm,online trajectory planning algorithm based on convex optimization and guidance law for large thrust-to-weight ratio rocket without hover,parameter optimization design for adapt to large static instability and sloshing structure of pole-zero,and active disturbance rejection attitude control algorithm.The numerical results indicate that it’s an efficient scheme above for vertical landing.
