Application of digital filter in Micro-inertial measurement unit System

摘要：

Micro-inertial measurement unit is the new international technique developed in recent years.As an independence system, it doesnt rely on any external information,neither radiate energy outwards. It has the characteristics such as the high data renewal rate,short-term accuracy and good stability. But the noise of the inertia component input signal is a central error source of MIMU system. Therefore along with the system rising demand for accuracy,how to reduce the system noise effect becomes a very central tache.This article brings forward an approach to improve the accuracy of MIMU system through digital filtering technique, introduces the process to design digital filter and designs a digital filter accord with this system.The result has been proved to be effective that noise of system is reduced and performance of system is advanced by analysing test data.
