光纤陀螺随机误差的滤波方案的探讨

范跃祖，宁文如，刘剑．光纤陀螺随机误差的滤波方案的探讨．数理统计与管理，１９９７，１６（４），２９～３２．光纤陀螺是新一代的光学陀螺仪，它的性能决定着惯性参照系统的精度。光纤陀螺的误差分为两大类。一类是有规律的，另一类是随机的。本文提出了两种新的用于光纤陀螺随机误差补偿的Ｋａｌｍａｎ滤波方案，考虑了两种随机模型：（Ⅰ）角速度变化为等随机的；（Ⅱ）角速度变化为等随机加速的。仿真结果表明，第二种方案对噪声起到了很好的抑制作用和滤波效果

Filter Program Research of Fiber Optic Gyro in Stochastic Error

Fiber Optic Gyro is a new generation optical gyro, its performance decides the accuracy of Inertial Reference System.The error of fiber optic gyro is divided into two parts, one is stochastic and the other is regular.This paper adopt the method of Kalman filter to compensate the stochastic error of fiber optic gyro.There are two programs analysed:1) Constant angular velocity adds to stochastic noise.2) constant angular acceleration adds to stochastic noise.The results of simulation show that the second program is more better to restrain the signal noise and to achieve good filter effect.
