Abstract: | 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. |
