摘　　要：为了减少微机械陀螺(MEMS)的误差并提高其精度,利用Allan方差法分析了MEMS陀螺的随机误差。介绍了Allan方差法的有关概念和计算方法,分析了MEMS陀螺的随机误差特性,通过对实测数据的分析处理确定了陀螺的误差系数,并与技术文档中给出的参数比较,对陀螺精度进行了评价。In order to reduce errors in MEMS gyroscopes to improve its performance, the stochastic error of the MEMS gyroscopes is analyzed by the Allan variance method. The paper introduced the Allan variance, analyzed the characteristic of noise observed in the MEMS gyroscope, calculated parameters of different errors and made compare with the value given in the user manual and made estimation for each gyroscope.
