Abstract
For validation of line of sight stabilization of space telescope,a structure﹣optics﹣disturbance﹣attitude control﹣image stabilization control﹣optics integrated modeling method is adopted.Accord﹣ing to the physical relationship,the disturbance model,the structure model of the satellite,the attitude control system model,the image stabilization control system model and the optical sys﹣tem model are integrated.As a result,the in﹣orbit line of sight jitter as well as the transfer char﹣acteristics from the disturbance to LOS (Line of Sight)jitter can be predicted.With an example of a space telescope,the LOS jitter under different LOS stabilization method and the transfer characteristics of the disturbance and noise are analyzed.It is demonstrated that with the integrat﹣ed modeling and analysis method the full frequency band LOS jitter can be got,and the LOS sta﹣bilization method of the space telescope is validated.关键词
