摘要
为满足高机动装甲车辆对光电瞄准系统视轴高稳定精度的要求,设计了光路中嵌入快速反射镜的反射镜式光电系统复合轴稳定平台。首先,利用施奈尔反射镜定律的矢量方程,构建系统视轴矢量方程,研究其运动特性、稳定补偿原理;然后,分析了控制方法、控制系统频率特性,分析结果显示,传统稳定平台控制系统的截止频率26 Hz,而复合控制系统的截止频率为215 Hz,控制系统带宽提升了8倍以上;最后,构建了复合轴稳定平台实验装置、测试装置,介绍了实验方法、稳定精度测试原理,开展了复合轴平台与传统平台的稳定精度比较实验。实验结果表明,在相同的实验条件下,复合轴平台较传统平台的稳定精度提高了5倍以上,反射镜式光电系统光路内嵌复合轴稳定平台能够实现光电瞄准镜的高精度稳定。
According to the requirements of high-stability accuracy electro-optic systems for high-mobility armored vehicles, a stabilization platform of complex axes for electro-optic systems with upside mirrors was designed, which embeds a fast steering mirror into the optical path. First, using the vector equation of Schneier's law of reflection, the vector equation of the line of sight is calculated, and the movement characteristics and compensation theory of stabilization for complex axes are studied. Second, the controlling method and frequency characteristics of the control system are analyzed. The results show that the cut-off frequency of complex axes platform control system, which is 215 Hz, is eight times that of the traditional platform control systems, which is 26 Hz. Finally, an experimental device and test equipment of the complex-axes platform are established, and the experimental method and testing principle of stability accuracy are introduced. Furthermore, the comparison experiments of stability accuracy between the complex-axes and traditional platforms are discussed. The experimental results indicate that the stability accuracy of the complex-axes platform is five times that of traditional platforms under the same experimental conditions, and a stabilization platform of complex-axes embedded into the optical path of an electro-optic system with upside mirrors can realize high-accuracy stability of electro-optic systems.
