| 摘 要： | 针对基于微机械陀螺的MIMU关键技术，对其进行研究和解决。参加美国JDAM性能指标和导航精度要求，计算陀螺性能参数：采用多级大容量的滤波器及有源电流限制电路，同时电源的输入端接入EMC滤波器，以提高电磁兼容性，并能抵抗浪涌和拉偏的能力；DSP实现信号实时采集，采用高次多项式拟合预处理去除数据野值；根据GJB729评估方法，利用利用蒙特卡罗方法仿真进行精度评估；最后按照GJB813进行可靠性分析。

| Abstract: | The key technologies of MIMU were studied and solved, Referred to the specification of JDAM performance and the navigation precision, the gyro performance parameters were computed. The EMC, surge wave and down-deflection performances were improved by multi-filter, power restriction electric circuit and EMC filter. The real time signal was collected by DSP, and the error values were removed by polynomial fit pretreatment. According to GJB729 and GJB813, the precision was evaluated by Monte Carlo simulation, and the reliability was analyzed. |
