加速度计动态误差系数标定的仿真研究

Research on simulation of calibrating dynamic error parameters of accelerometer

为了简化加速度计动态误差系数的标定过程,缩短标定试验时间,在建立加速度计动态误差数学模型的基础上,结合三轴转台模型及测试原理,一次性标定出加速度计动态误差系数,同时避免了角振动台的使用。最后利用MATLAB软件进行仿真试验,得到了较好的结果。

Consider to simplifying the process of calibrating dynamic error parameters of accelerometer and shortening the time of calibrating test, all dynamic error parameters are calibrated at one-time, based on the mathematic model of dynamic error of accelerometer and integrating the model and the testing theory of the three-axis turntable, meanwhile, the angle-vibration table is avoided. MATLAB is adopted to carry out simulated test in the last part of this paper and the preferable result is acquired.
