MHD角速度传感器随机漂移误差补偿方法研究
Study on MHD Angular Rate Sensor's RandomDrift Error Compensation Method
摘要
Abstract
In order to compensate the random drift error of Magnetohydrodynamics(MHD)angular rate sensor effectively,Kalman filter algorithm is used to process the random drift of MHD angular rate sensor on the basis of the time sequence model of the MHD angular rate sensor.And then,variance and Allan variance are used to analysis and compare the data before and after filtering.Finally,the experiment result demonstrate the effectiveness of the method improving the accuracy of MHD angular rate sensor.关键词
