摘要
主要介绍了一种微机械系统(MEMS)陀螺仪的速率标定法,根据MEMS陀螺仪的输出数学模型,详细推导了如何得到MEMS陀螺仪的输出数学模型中的零漂、刻度因数和安装误差,并在得到其标定系数后将其封装在C函数中进行验证实验。通过实验数据分析可知,MEMS陀螺仪速率标定法原理简单,易于实现,且精度较高。此标定法所得到的MEMS陀螺仪输出数学模型能较准确地反映其输出,且MEMS陀螺仪的线性度有所改善。
A velocity calibration method of MEMS gryoscope has been introduced in this paper.The zero drift,scale factor and the installation error in the mathematic model of MEMS gyroscope has been derived based on the output model of MEMS gyroscope.After obtaining the calibration coeffiient,it was encapsulated in the function of C to be verified experimentally.The experiment results showed that this velocity calibration method was simple in principle,easy to realize and high accuracy.The output model of MEMS gyroscope can reflect its output accurately.The linearity of MEMS gyroscope has been improved.
