Fiber-optic gyroscope closed-loop control method based on segmented sampling and filtering

The invention provides a fiber-optic gyroscope closed-loop control method based on segmented sampling filtering, which can reduce the noise of a fiber-optic gyroscope system and improve the signal-to-noise ratio of the system. Starting from closed-loop control in the gyroscope, the method can reduce the noise when the angular motion of the fiber-optic gyroscope is measured, improve the signal-to-noise ratio of the output signal, and is favorable for improving the measurement precision of the fiber-optic gyroscope and improving the tracking performance and the dynamic performance of a closed-loop system. 本发明提出了一种基于分段采样滤波的光纤陀螺闭环控制方法，能够降低光纤陀螺系统的噪声，提高系统的信噪比。本发明从陀螺内部闭环控制着手，能够降低光纤陀螺测量角运动时的噪声，提高输出信号的信噪比，有利于提升光纤陀螺的测量精度，改善闭环系统的跟踪性能和动态性能。
