摘要
针对陀螺稳定平台动态漂移测试需求,提出了一种利用反馈锁定法构建基于激光位敏探测(PSD)技术的平台动态漂移测试系统的方案。通过对开、闭环两种测试状态的分析推导,换算出了闭环测试状态下的技术指标数据,充实了工业部门所发技术文件中的内容。实验结果表明,该系统可精确分离出平台的动态误差和动态漂移,测试结果直观,可信度和精度都很高。
In accordence with the demand of gyro-stable platform dynamic drift test,a scheme of dynamic drift test system for gyro-stable Platform is presented by the method of feedback locking.Based on the analysis of the open loop test and the close loop test,the specification of close loop test is calculated,which filled up the blank of the document offered by the department of aerospace industry.The experimental results show that the dynamic drift and the dynamic error of the gyro-stable platform are accurately separated,and the test result is intuitionistic,reliable and accurate.
