摘要
根据加速度计参数模型辨识的需要,通过采集加速度计零偏,分析了数据的特点,结合最小二乘、递推最小二乘、最大似然估计3种系统辨识方法,建立起零偏数据相关的数学模型,再通过对模型进行仿真,观察参数变化曲线趋势,把模型参数和辨识之后的模型参数作对比,证明了模型的可靠性。
In this paper,according to the need of the accelerometer parameters model identification,the accelerometer zero bias through gathering,analyzes the characteristics of the data,combining three methods of system identification,the least squares,the recursive least squares and maximum likelihood estimate,relevant mathematics models were established zero deflection data,the simulation based on the model,to observe parameters changing trend of curve,the model parameters and to identify the parameters in the model after comparison,proves the reliability of the model,for accelerometer parameters change with time of level provides a reference method.
