Zero Drift Random Error Compensating Methods for MEMS Gyros Based on Polynomial Fitting Algorithnm
摘要
Abstract
The undesirable accuracy of MEMS sensor limits the range of its application. The compensating method for 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 improve navigation accuracy effectively.关键词
