Basic working principle and structure model of accelerometer is introduced

and then differential equations of accelerometer is converted to difference equation

on the basis of traditional least squares method identification

using identification method of recursive augmented matrix

parameters model of accelerometer are identified. Identification simulation is carried out by Matlab

parameter estimation value and curve graph is obtained

it shows that using recursive augmented matrix identification methods to identify system parameter identification has advantages of fast speed

high identification

accurate identification results

and so on.
