| 摘 要： | 从工程实用的角度出发,探讨了MEMS陀螺仪随机漂移误差的有效补偿方法.首先采用时间序列分析的方法建立了MEMS陀螺仪的随机漂移误差模型,然后阐述了用基于时间序列模型的Kalman滤波方法减小该漂移误差的具体方法.对某MEMS陀螺仪实测数据的误差补偿结果表明,所介绍的滤波方法能够有效地抑制其漂移误差,提高MEMS陀螺仪在实际系统中使用精度.

| Abstract: | The compensating method for MEMS gyroscope random drift error is discussed. First its drift error model is created by using the time-serial analysis, then the process of decreasing this drift error by making use of Kalman filter based on the above error model is expounded. The compensating results for the practical testing data of a MEMS gyroscope show, the drift error can be controlled effectively by the filtering method presented, and its application precision in practical system can be further proved. |
