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.

Key words

high flexible structure / vibration suppression / positive position feedback / suppression of the whole panel
