摘要: 针对一类大挠性机动飞行器,同时进行的姿态和轨道机动将激发挠性结构与中心刚体之间的平移耦合模态和转动耦合模态。为了提高姿态和轨道控制稳定度,提出了一种整合的改进型正向位置反馈(MPPF)控制方法抑制挠性结构的振动。首先建立了包含转动耦合和平移耦合模态的动力学模型,推导了耦合模态参数,然后基于MPPF控制律,设计了对转动耦合模态和平移耦合模态同时进行抑制的主动振动控制器,并采用M范数方法进行了参数优化,采用压电智能材料构建了主动振动控制系统。仿真结果表明所设计的控制器能够对机动飞行器的挠性结构振动起到很好的抑制效果,并且提高了姿态和轨道的控制稳定度。

Abstract: Considering maneuvering spacecraft with high flexible appendages, the translational and rotational coupling vibration modes between flexible structures and center rigid body are excited by the simultaneous attitude and orbit maneuvering. Aimed at higher stability of attitude and orbit control of spacecraft, an integrated modified positive position feedback (MPPF) controller is proposed to suppress the vibration of flexible structure. First, dynamic model is established with translational and rotational coupling effects considered, and coupling mode parameters are calculated. Then, an integrated controller was designed to suppress the translational and rotational coupling vibration modes based on MPPF. Controller parameters were optimized through M-norm optimization method. Active vibration control system is constructed using piezoelectric smart material. The simulation results show that the proposed controller is efficient on vibration suppression of the flexible structures and the stability of attitude and orbit control of maneuvering spacecraft is improved.

Key words: flexible spacecraft, maneuvering, vibration control, coupling dynamics, modified positive position feedback (MPPF)
