摘要
光纤陀螺本身存在着诸多噪声源,考虑到其作为惯性导航系统的核心器件,陀螺的噪声和零偏稳定性成为系统性能实现的关键。为抑制陀螺的噪声、提高随机游走系数(RWC)性能,本文分析了影响陀螺随机游走系数的几种重要因素,提出了可通过匹配光纤陀螺参数、选择合适的调试技术来降低RWC,提高陀螺性能的方法。设计影响RWC的相关实验,在大量实测数据分析的基础上,通过光纤陀螺匹配合适参数,提高了陀螺RWC的性能水平。另外,在分析实验得到的陀螺采样时各采样参数数据,确定了各采样参数和RWC的关系,随后提出了一种合理确定陀螺采样占空比的方法。
Fiber optic gyroscope has a lot of noise sources, which is the core component of the inertial navigation system. The noise and the zero bias stability of the gyroscope are the key to the performance of the system. In order to suppress the gyro noise, improve the random walk coefficient of performance(RWC), this paper analyzes the influence of FOG random walk coefficients of several important factors, put forward by matching the parameters of fiber optic gyroscope, choose suitable debugging techniques to reduce the RWC, methods to improve the performance of the gyro. Based on the analysis of a large number of measured data, the design of the RWC related experiments, the performance of the gyro RWC is improved by matching the appropriate parameters. In addition, the sampled data are sampled at the time of the analysis of the experiment, the relationship between sampling parameters and RWC is determined, and then a reasonable method to determine the duty cycle of fiber optic gyro is presenter.
