| 摘要: |
| 零燃料大角度姿态机动技术是新近应用在国际空间站的新概念姿态控制技术。构造了以控制力矩陀螺为执行机构的空间站姿态控制动力学模型，在此基础上，建立了空间站本体与控制力矩陀螺之间的角动量守恒关系。针对各类大角度姿态机动任务，通过分析空间站惯量参数与控制力矩陀螺性能参数之间的解析关系，得到了零燃料大角度姿态机动路径的存在性条件。通过规划算例验证了存在性分析的正确性。所提出的零燃料大角度姿态机动存在性条件，为姿态机动路径的存在性判断提供了便捷可行的方法，为零燃料大角度姿态机动技术未来在我国空间站实施的可行性论证提供重要的理论依据。 |

| Abstract: |
| Zero-propellant maneuver is an advanced concept of attitude control, which has been applied to the International Space Station. The dynamic models of space station using control momentum gyros are constructed, and the momentum equilibrium relation between space station and control momentum gyros is established. Then, considering different large angle attitude mission, the relation between inertia of space station and characteristic parameters of control momentum gyros is analyzed, and conditions of zero-propellant maneuver path existence are obtained. Effectiveness of the existence conditions is verified by the path planning examples. The proposed existence conditions can provide a convenient and effective method to determinate whether the zero-propellant maneuver path exists, which can provide significant theoretical argument for zero-propellant maneuver technology to apply to Chinese Space Station in future. |
