针对反射镜视轴稳定平台特点,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稳定平台视轴惯性角速度进行数学重建, 同时分析了反射镜转角和视场范围的关系. 为克服反射镜固有的2:1特性,对比了传统的机械稳定控制方法,和重建光轴的半捷联稳定方法. 仿真结果表明:两种方法都可以稳定视轴,但重建视轴的半捷联控制方法符合稳定平台小型化的发展趋势.

According to the characteristics of the line-of-sight kinematics in mirror stabilization platform, a general method based on the artificial mass stabilization platform was used to reconstruct LOS angle rate by utilizing the basic mirror kinematics equations. Then the relation between mirror rotation and the field-of-view was figured out. Due to the law of reflection, an auxiliary shaft must be made for mechanical mass stabilization or semi-strapdown stabilization. Analyzing this two methods deeply show that the methods are both feasible for mirror LOS stabilization control, but semi-strapdown stabilization would accord with the future needs.
