光电系统扰动隔离度指标测试方法

Methods for testing disturbance isolation of EO system

在推导出光电跟踪仪扰动隔离度计算公式的基础上,给出了2种测试扰动隔离度的方法:基于模拟环境测试方案和载体平台测试方案。通过分析2种测试方案的试验数据,分别阐述了它们的优缺点和适用的场合,并指出速度环的带宽是影响双环路控制模式下系统隔离扰动能力的关键因素,最后提出了增加扰动隔离度的控制模式优化建议。

According to the derived calculation formula of disturbance isolation of optoelectronic tracking device,two methods for testing disturbance isolation were given:simulation environment test scheme and platform test scheme.Through analyzing the experimental data of the two testing methods,the advantages,disadvantages and their applications were elaborated.It was pointed out that the bandwidth of speed loop was the key factor to influence the disturbance isolation ability of system under the double-loop control mode.Additional,the optimization solution for control mode of disturbance isolation was suggested to add.
