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.
