| 摘 要： | 在分析激光陀螺的数学模型和三欠样条函数拟合原理的基础上，针对俄罗斯某型低精度激光陀螺实际输入－输出特性曲线的数据，应用三次样条合方法进行分析处理，推导出了适用于非线性工作范围误差补偿且实际陀螺特性的数学模型。本文所提方法可用于工作区线性化较差，工作精度低的激光陀螺的精度补偿。

| Abstract: | Based on the analysis of mathematic model of ring laser gyro (RLG) and the principle ofcubic spline data interpolation,pointing to the data of practical input-output characteristic curve of someRussian model of RLG and making analysis and treatment with the cubic spline data interpolationmethod,the mathematic model applying to error compensation in the nonlinear working range and beingaccordance with the practical gyro characteristic has been deduced. The method proposed in this papercan be applied to accuracy compensation of the RLG with worse linearity and lower working accuracy inthe working range. |
