| 摘 要： | 挠性卫星在快速机动中既要满足快速性要求，又要抑制挠性附件产生的振动。文章提出了一种基于非约束模态方程的方波序列控制方法，并给出了最小机动时间的方波规划方法。该方法不仅保证机动后无余振，而且满足最快机动的要求；此外，由于控制输出为方波，因而适合卫星的喷气推力器控制模式和飞轮控制模式，最后通过数字仿真验证了方波序列控制的有效性。

| Abstract: | Fast maneuver of flexible satellite system often requires large attitude changing with reduction of vibration. In this paper, pulse sequence control methodology is presented based on unconstrained mode equations to suppress residual vibration; besides, pulse sequence programming is proposed to minimize maneuvering time. The methods can meet the requirements of the fast maneuver and without residual vibration after maneuvering. Moreover, it is very suitable to satellite systems equipped with on off jets and reaction wheels. Finally, numeric simulation is explored to verify the validity of pulse sequence control. |
