本研究提出了一种用于具有大量燃料的太空着陆器的下降控制系统,以保护着陆器在微重力物体上着陆时免于倾覆。由于晃动是下降过程中的一个主要问题,因此需要构建一个考虑晃动动力学的控制系统。我们推导出一个模型的着陆器考虑燃料动力学,确定燃料的最佳轨迹的指导,设计一个燃料状态估计器的导航,并设计一个跟踪控制器。所提出的方法的有效性进行评估,使用物理模拟器。所提出的方法实现了同时稳定的着陆器和燃料,并被证明是有效的,在防止倾覆。
This study proposes a descent control system for a space lander with a large amount of fuel, to protect the lander from overturning when landing on microgravity objects. As sloshing is a major problem during descent, it is desirable to construct a control system that considers the sloshing dynamics. We derive a model of the lander considering fuel dynamics, determine the fuel-optimal trajectory for guidance, design a fuel state estimator for navigation, and design a tracking controller. The effectiveness of the proposed method is evaluated using a physical simulator. The proposed method achieves simultaneous stabilization of the lander and fuel, and is shown to be effective in preventing overturning.
