| 摘 要： | 针对挠性航天器姿态机动控制中存在的参数不确定性、外部干扰、挠性附件振动及挠性模态不易直接测量的问题,提出一种具有干扰抑制的自适应输出反馈机动控制器设计方法.设计中无需忽略挠性附件和中心刚体的耦合,利用挠性附件固有物理特性构造一种结构简单的开环模态观测器,然后用以此获得的模态估计信息及可测量的姿态四元数和角速度信息,基于...

| Abstract: | According to the attitude maneuver control problem of a flexible spacecraft with parametric uncertainties,external disturbances,elastic vibration and the unmeasured vibration variables,a design scheme is proposed for an adaptive output feedback maneuver controller with disturbance attenuation.In the design of this controller,the coupling between flexible appendage and rigid body was not neglected.An open-loop modal observer with simple structure was constructed by utilizing the inherent physical properties ... |
