Abstract

This paper studies solar sail heliocentric inclined elliptic displaced orbits (HIEDOs) with the application of reflectivity control devices (RCDs). In the solar sail HIEDO, the angle between the line from the Sun to the focus and the elliptic orbital plane is variable. A novel method is given to solve the sail attitude angles and the state of RCDs to achieve HIEDOs. Furthermore, this paper analyzes the problem of multiple solar sail formation flying (MSSFF) around HIEDOs, which consists of a chief and multiple deputies. The chief moves in an HIEDO and does not need to obtain the information from the deputies. The deputies need to receive the information from the chief, and an undirected connected graph is adopted to represent the information exchange structure between the deputies. Considering the convergence speed and reliability of the solar sail formation system, an innovative finite-time fault-tolerant distributed coordinated control scheme is devised. Under this control scheme, the deputies can consistently converge to the expected solar sail formation configuration within a finite time, even in the presence of the actuator effectiveness faults within a certain range. Finally, an example is used to verify the validity of the designed control scheme.

绕日心倾斜椭圆轨道飞行的多太阳帆编队有限时间容错一致性控制

利用反射率控制装置（rcd）研究了太阳帆日心倾斜椭圆位移轨道（hiedo）。在太阳帆HIEDO中，太阳到焦点的直线与椭圆轨道平面之间的夹角是可变的。提出了一种求解风帆姿态角和rcd状态的新方法来实现hiedo。在此基础上，分析了由一个主帆和多个副帆组成的多太阳帆编队飞行问题。局长在HIEDO中移动，不需要从副手那里获得信息。代表需要从局长那里接收信息，采用无向连通图表示代表之间的信息交换结构。考虑到太阳帆编队系统的收敛速度和可靠性，设计了一种创新的有限时间容错分布式协调控制方案。在该控制方案下，即使执行器在一定范围内存在有效性故障，副手也能在有限时间内一致收敛到期望的太阳帆编队构型。最后，通过算例验证了所设计控制方案的有效性。此图像的替代文本可能是使用AI生成的。
