| 摘 要： | 分析了MEMS惯性测量组件(MIMU)的主要误差源,采用功率谱密度(PSD)法和Allan方差法对MIMU进行了随机误差分析、建模和估计研究。将随机误差中的量化噪声、闪烁噪声及随机游走噪声等误差成分分离出来,并对其统计特性进行了估计,实验数据分析表明闪烁噪声和随机游走误差在MIMU随机误差中占主要分量。

| Abstract: | The main error sources of MEMS inertial measurement unit are studied.Power spectral density(PSD) and Allan variance method are used for analyzing,modeling and estimating of the MIMU stochastic errors.The quantization noise,flicker noise,random walk noise and other noises are separated from error source,and its statistic characteristic is estimated.The test results show that flicker noise and random walk noise are main stochastic noise of MIMU. |
