空间大口径望远镜稳像系统发展现状及趋势

介绍了目前国际上已发射及正在论证的大型空间望远镜的稳像控制系统，主要包括自由飞行模式的HUBBLE、JWST、ATLAST-8m和ATLAST-9.2m，载体搭载模式的SOFIA和OPTⅡX。详细论述了这些空间望远镜稳像系统的组成、工作原理、主要元件、性能指标和控制算法，并对基于磁悬浮技术的无扰动载荷设计概念和机械臂直接驱动空间相机的设计思想进行了介绍。分析表明，基于机械臂和磁悬浮技术的精密稳像及主动振动抑制系统是未来的发展趋势。

Current status and development tendency of image stabilization system of large aperture space telescope

In this paper , the image stabilization system of large aperture space telescope on orbit or being de-signed is introduced, including HUBBLE, JWST, ATLAST-8m and ATLAST-16m in free flying mode, and SOFIA, OPTIIX in space-borne mode .The composition , working principle , major component , performance requirements and control algorithm of image stabilization system are discussed in detail .Then, the disturb-ance-free payload design concept based on the magnetically suspend technology and design idea of space tele -scope directly driven by the manipulator are introduced .Analysis results indicate that the precise image stabi-lization and active vibration isolation system based on the magnetically suspend and manipulator technology is the future development tendency .
