摘要

根据太阳电池翼的结构固有频率和模态阻尼参数，设计基于零位移算法的输入整形器，用于抑制太阳电池翼调姿后的残余振动。分别用太阳电池翼有限元模型的动力响应仿真和缩比模型试验测试，验证了整形后的转角输入函数驱动太阳电池翼调姿能抑制残余振动，且具有较强的鲁棒性。

Abstract

According to the natural frequencies and modal damping parameters of the structural system, an input shaper based on zero-placement is designed and used to suppress the residual vibration. Through the dynamics response simulation of the finite element model of the solar array, it is verified that shaped rotation input function to drive the attitude adjustment of the solar array can suppress the residual vibration, and have a better robustness. At last, the zero-placement input shaper which can reduce efficiently the residual vibration is verified experimentally through the scaled model of the solar array.
