摘要
MEMS(Micro-Electro-Mechanical Systems)传感器精度相对较低限制了其应用范围,从实际工程应用出发,针对MEMS陀螺仪零点随机漂移误差探讨了有效的补偿方法。推导了不同阶数拟合曲线的回归方程,根据实测MEMS陀螺零点数据对不同阶数拟合曲线的补偿效果进行对比,选取最优方案并通过跑车试验进行验证,证明该方法能够有效抑制陀螺仪零点漂移误差,提高微惯性导航系统的导航精度。
The undesirable accuracy of MEMS sensor limits the range of its application. The compensating methodfor MEMS gyroscope random drift error is discussed. According to actual test data of gyroscope,the equation of fit-ting curve was deduced and compensating effect of different kinds of fitting methods were compared. The car experi-ments were carried out to prove that this compensating method can restrain drift random error of gyros and improvenavigation accuracy effectively.
