标题： Attitude Control of Solar Sail with Reflectivity Control Devices

摘要： 太阳帆提供了一种无燃料推进的有前景的解决方案，使新型任务剖面和更深层次的空间探索成为可能。尽管飞轮是航天器姿态控制的标准配置，但太阳帆较大的转动惯量常常导致飞轮频繁饱和，需要通过额外的控制方法来卸载动量。磁力矩器历史上被用于此目的。本文研究了反射率控制装置（RCDs）作为动量管理的一种替代方法，旨在防止飞轮饱和。开发了一个处于太阳同步轨道中的太阳帆的动力学模型，并结合干扰力矩来评估控制效果。数值模拟评估了RCDs在卸载飞轮动量和防止饱和方面的有效性。结果显示，RCDs在地球轨道上还有其他应用，并且在磁力矩器无法使用的深空任务中也有潜力。 显示英文摘要

摘要： Solar sails offer a promising solution for fuel free propulsion, enabling novel mission profiles and deeper space exploration. While reaction wheels are standard for spacecraft attitude control, the large moment of inertia of solar sails often lead to frequent reaction wheel saturation, necessitating momentum offloading via additional control methods. Magnetorquers have historically been used for this purpose. This paper investigates Reflectivity Control Devices (RCDs) as an alternative method for momentum management, aiming to prevent reaction wheel saturation. A dynamic model of a solar sail in a Sun synchronous orbit is developed, incorporating disturbance torques to assess control. Numerical simulations evaluate the effectiveness of RCDs in offloading reaction wheel momentum and preventing saturation. The results indicate additional applications for RCDs in Earth orbit as well as potential for deep space missions where magnetorquers cannot be used.
