摘要针对基频低于1Hz的大挠性太阳帆板，提出了整板主动振动抑制方法。该方法通过在太阳帆板上集成压电元件作为传感器和执行器；针对帆板挠性增大时，同位控制易出现虚假抑制的现象，综合考虑压电传感器的测量数据和板上一点的振动情况，基于正向位置反馈控制律（PPF, Positive Position Feedback），设计了整板振动抑制控制系统。通过Adams和Simulink联合仿真，对控制系统的振动抑制能力进行了考核，结果表明所设计的PPF控制系统避免了虚假抑制，具有良好的整板振动抑制效果。
Abstract：In this paper, an active vibration suppression method is proposed for flexible solar panels with first-order frequency less than 1 Hz. The method employs piezoelectric elements, which are integrated into the solar panel, as sensors and actuators. However, with the decrease of the first-order frequency, collocated control may cause unreal suppression. To avoid unreal suppression, both the measurement from the sensors and the vibration of an aim point on the panel are taken into account in designing the positive position feedback (PPF) controller. The proposed method is validated by simulation based on Simulink and Adams. Results show the effectiveness on vibration suppression of the whole panel.
