摘要
针对高速运动的车辆对光电系统的需求, 提出利用快速反射镜代替原有平面反射镜, 构建上反射镜式光电系统复合轴稳定平台, 并通过理论分析, 推导出该平台的瞄准线矢量方程, 分析瞄准线的运动特性、复合轴稳定补偿原理及控制方法, 并且比较了其与传统一级稳定平台在系统带宽、隔离度方面差异, 最后, 针对实际工程应用, 研究复合轴二级平台轴系安装误差对系统误差的影响。研究结果表明: 上反射镜式光电系统稳定复合轴平台实现了对一级平台稳定误差的补偿, 系统带宽接近快速反射镜带宽, 约为200 Hz, 大幅度提升了系统稳定精度, 但是系统对二级平台的安装误差相对比较高, 其误差需要小于0.05 mrad。
Abstract
In order to design optics-eletricity system for high speed vehicle, the mirror is replaced by fast steering mirror, and stabilization platform of complex axes is designed for optics-eletricity system with upside mirror. Through theory analysis, vector equation of line of sight for the platform was calculated, movement characteristic and compensation theory of stabilization for complex axes was analyzed, and controlling method of complex platform was presented. In the end, influence of assembly axes error to system error was studied for engineering application. The research result indicate that , Stabilization platform of complex axes for optics-eletricity system with upside mirror implement compensation to error of first platform, bandwidth of system is 200 Hz, which is approximately equal to bandwith of fast steering mirror, and stabilization precision of system is upgraded, but assembly error of second platform should less than 0.05 mrad.
