帆板驱动微振动对卫星的影响与对策

摘要

基于帆板驱动机构精确建模，对帆板及其驱动带来的影响进行分析；在分析帆板驱动特性的基础上，给出了微振动测试数据及其分析结果；并以某卫星为例给出了帆板驱动控制时微振动对姿态的影响，提出了频率约束和振动主动抑制控制相结合的解决措施及验证结果。%The measurement data and analysis result of the micro-vibration responses of a solar array drive mechanism are given. Then, based on the exact dynamic modeling of the solar array drive system, the influence of the micro-vibration on the attitude of a typical satellite is analyzed. Finally, the integrated measures by using frequency restriction method and active vibration suppression method are proposed, and the corresponding simulation result is given.
