MEMS三轴加速度计6位置标定方法的研究
The Research on Six-Position Calibration of MEMS Three Axis Accelerometer
摘要
Abstract
Aiming at the problem of long time which twelve-position calibration in the research team encountered, six-position calibration of MEMS three-axis accelerometer is proposed. Firstly,the input and output model of three axis accelerometer is established,and the position arrangement and procedure of six position calibration are intro⁃duced in detail,then the calculation method of the mathematical model parameters including scale factor,installa⁃tion error coefficient and zero bias value are given. Finally,three-axis turntable experiment verified the feasibility of the six position calibration method and the accuracy of the model. The experiment results show that the six position calibration method is simple and feasible,and the accuracy can be improved by 1~2 magnitudes after compensa⁃tion,this lays the theoretical foundation of its engineering practicability.关键词
