摘要
文章对超静平台在卫星高精度高稳定度指向控制中的应用进行了研究,针对不同频率振源下平台的动力学模型,设计了超静平台分层控制器。通过控制算法仿真表明,采用超静平台能充分消除星上振源对有效载荷的干扰,保持对观测目标精确指向。
The ultra quiet platform is used to achieve high pointing accuracy and high stability control of satellite in this article.Several models of ultra quiet platform are built according to different frequencies and different controllers are designed.The simulation of platform shows that the payload can isolate vibrations of satellite and keep pointing to the target precisely with ultra quiet platform.
