摘要
文章从工程角度出发,介绍了一种将MEMS陀螺仪的静态误差项和动态误差项(即确定性误差项)一并辨识的方法,运用解析法与实验法结合的技术,快速辨识陀螺仪确定性误差项。该方法只需一个单轴转台,可以识别单轴至三轴的MEMS陀螺仪确定性误差项。并以STIM202 MEMS陀螺仪为例,对整个方法的实验步骤和解算步骤做了详细的说明,并对比了不同解算方法下的结果差别,该方法可以扩展到激光陀螺仪、光纤陀螺仪、加速度计等主流惯性器件的确定性误差项辨识工作,为从事相关行业的技术人员提供一种思路。
This paper introduces an efficient way to identify the MEMS gyroscope＇s static error terms and dynamic error terms which are called deterministic error terms together from an engineering point of view by using a combination of analytical and experimental methods.It only needs a single-axis turn table and you can identify the terms from single-axis MEMS gyroscope to a three axes.We take STIM202 MEMS gyroscopes as an example to explain the experimental methods and solver steps and have a comparison of the results of the differences under different solution methods.In conclusion we think this method can be extended to recognize the work of the deterministic error terms from laser gyroscopes,fiber optic gyroscopes,accelerometers and other mainstream inertial devices and hope to provide an idea for technical personnel engaged in related industries.
