Line-of-sight stabilization techniques for mirror electro-optical platform

  • 摘要: 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。

     

    Abstract: According to diversity characteristics of the line-of-sight(LOS) kinematics in various mirror platforms, a general method based on the artificial mass stabilization platform was proposed to reconstruct LOS inertial angle rate in various mirror platforms by employing the basic mirror kinematics equations. Then, the LOS kinematics and the LOS stabilization techniques of several common mirror platforms just like the typical single mirror platform, the special configuration single mirror platform, the polar coordinate multi-mirror platform and the orthogonal coordinate multi-mirror platform were analyzed deeply. Lastly, the simulation results of elevation gimbal for the typical single mirror platform show that the method based on the artificial mass stabilization platform is feasible for various mirror LOS stabilization control.
