Research of Noise Suppression for MEMS Gyro ADXRS150
The random drift of MEMS gyro is too large due to these effects of external environmental factors and manufacturing imperfect. In order to compensate the random drift error of an ADXRS150 MEMS gyro, in this paper, the output of ADXRS1S0 in static are sampled. Then based on the time series theory, ARIMA model of ADXRSI50 output data is established. Taken this model as the state equation and the sampled data as the measurement equation, the Kalman filter is designed to process the data. These conclusions in the final part of this paper indicate that the model and the filtering method can restrain the gyro noise of the MEMS gyro ADXRS150 and improve its precision effectively and greatly.
