Abstract
To avoid the shortcomings of the compensation of null output of MEMS gyroscopes,this paper presents a null shift compensation model for MEMS gyroscopes based on temperature constraint model.Firstly,according to the measurement model of MEMS gyros' signal,which consists of the definite error and the stochastic one.The temperature-null bias voltage constraint model and temperature-main frequency constraint model are proposed on the definite error effected by temperature.And the models can weaken the defmite and season parts effectively.Then,the ARMA model is used to predict the rest stochastic error of MEMS gyros' signal.At last,Kalman filter is made by optimizing the established ARMA model,which aims at the improvement of the model's performance.The theoretical analysis and experimental results show the robust and efficiency of the model proposed.关键词
