The Spacecraft Modal Parameter Identification Based on the Sine-Swept Vibration Test 基于正弦振动试验的航天器结构模态参数识别
In using infrared heating cage to simulate external heat flux on spacecraft, a fine control of heat flux or temperature requires an accurate identification of the temperature model. 用红外加热笼进行航天器外热流模拟时,要获得热流、温度的优良控制品质,前提是需要准确辨识被控对象模型。
The method for sensing spacecraft attitude with stellar map is analyzed in the paper. The simulation experiments were carried out under the different conditions when star was brighter than 6 m with SAO star catalogue and the corresponding identification probability is achieved. 分析了用恒星星图进行航天器姿态敏感的方法,并用SAO星表在亮于6m的情况下,进行了多种条件下的仿真实验,获取了相应的识别几率。
