摘要
在分析激光陀螺的数学模型和最小二乘法原理的基础上，针对某型低精度激光陀螺实际输入—输出特性曲线的数据，应用最小二乘原理的多项式拟合方法对数据分析处理，推导出了适用于非线性工作范围误差补偿且符合实际陀螺特性的数学模型。本方法适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。
Laser Gyros (RLG) have been applied in different navigation system widely due to it's high accuracy and higy performance, To reduce some nonlinear work period's effect on the measurement result, this paper present a method to calculate the model of RLG by a polynomial method of least-squares.The experiment showed that the method could deduce a mathematies model of RLG which could be used to compensate the error of nonlinear error and got a high accuracy of measurement.
