摘　　要：为实现高精度激光陀螺双轴旋转导航系统,通过理论分析,设计实现了双轴旋转导航系统所需的高精度转动控制方案。所设计的转动方案在实际旋转导航系统样机上进行了实验验证。实验结果表明,所设计的转动控制系统速率偏差优于2?10-5(°)/s,速率平稳度优于10-4,速率峰值波动优于3?10-3(°)/s,峰值定位误差优于0.001°。所设计的转动控制电路控制精度高,运行稳定可靠,很好地满足了研制激光陀螺双轴旋转导航系统样机的需求。To realize high-precision laser gyroscope dual-axis rotating inertial navigation systems（INS）, a high-precision rotating scheme for the INS is put forward through theoretical analysis. Then the rotating scheme system is tested in the actual dual-axis rotating INS. Tests results show that： the speed deviation is superior to 2×10^-5（°）/s, the speed accuracy is superior to10^-4, the maximum speed error is superior to 3×10^-3（°）/s, and the maximum position error is superior to 0.001°. The rotating scheme＇s circuit has such advantages as high-precision, high stability and reliability. The designed rotating scheme system meets the demands for developing the laser gyroscope dual-axis rotating INS.
