柔性航天器大角度机动闭环开关序列控制

针对柔性航天器大角度姿态机动时柔性附件的振动抑制问题，提出了一种闭环脉冲序列控制方法．该方法利用姿态角和角速度作为反馈信号，分别使用喷气推力器、反作用飞轮完成姿态的粗、精控制，以实现航天器的快速大角度机动；同时，为实现平稳的机动过程，设计成形的喷气开关控制指令，以避免机动过程中推力器激起柔性结构的持续振动．全物理实验结...

Closed-form on-off control for large angle maneuver of flexible spacecraft

A closed-form pulse train control algorithm is presented for vibration suppression of flexible spacecraft during large angle maneuver.Based on attitude angle and angular velocity,the control algorithm uses thrusters for coarse attitude control and reaction wheels for high precision attitude control at the final stage of operations.The input shaping is introduced to modulate thruster pulses with a set of properly timed impulses to suppress vibrations introduced by on-off control.Physical experiment results demonstrate that the proposed approach can significantly reduce the vibration of flexible appendages during fast large angle maneuver,and the presented control algorithm has the advantages of less fuel consumption,as well as simplicity and efficiency for practical on-board computer operation.
