| 摘要: |
| 针对卫星动态扫描成像任务中的姿态控制问题，建立卫星姿态动力学模型，分析动态扫描成像任务对姿态控制的特殊需求。结合动态扫描成像任务需求提出一种典型的姿态机动方案，对姿态机动过程所需控制力矩进行估计。基于期望力矩和星体实时姿态设计一种俯仰机动控制律，并提出五棱锥构型陀螺群的操纵方案。针对某动态扫描成像任务卫星，对提出的控制律进行数值仿真。仿真结果证明所提方案可以满足卫星动态扫描成像的姿态控制要求。 |

| Abstract: |
| According to the problem of attitude control of satellite dynamic scanning imaging, the dynamic model of the satellite attitude was built and the specific requirement of dynamic scanning imaging tasks for attitude control was analyzed. Combined with the dynamic scanning imaging tasks, a typically attitude maneuver scheme was designed. The required control moment of the process of dynamic scanning imaging was estimated. A pitching maneuver control law based on the expected torque and real-time attitude of satellite was developed, and the steering law of five pyramid configuration gyros was given. A numerical simulation was presented for the designed control law based on a maneuver task. The simulation results proved that the proposed scheme can satisfy the requirement of attitude control of dynamic scanning imaging satellite. |
