针对不同类型反射镜平台视轴运动多样性的特点,从基本的反射镜视轴运动学关系出发,采用基于虚拟整体稳定平台的视轴重建方法对反射镜平台视轴惯性角速度进行数学重建。同时,深入分析了常见的典型单反射镜平台、特殊配置单反射镜平台、极坐标多反射镜平台以及直角坐标多反射镜平台的视轴运动学关系和视轴稳定控制技术。基于典型单反射镜平台俯仰轴视轴稳定控制的数值仿真结果表明,采用虚拟整体稳定平台方法的视轴稳定控制技术用于反射镜视轴稳定控制是可行的。
According to the characteristics of boresight motion of different types of mirror platforms, the visual axis reconstruction of the boresight moment of inertia of the mirror platform is carried out based on the basic kinematics relationship of the mirror. At the same time, the common typical SLR platform, specially configured SLR platform, Polar multi-reflector platform and Cartesian coordinate multi-mirror platform are analyzed deeply and the visual axis stability control technology is also analyzed. The numerical simulation based on the boresight axis of a typical SLR platform shows that it is feasible to employ the boresight stabilization control technology based on the virtual monolithic stabilization platform for the boresight stabilization of the reflector.
