Subspace Identification based Modeling Research for Gyroscope Random Drift

Tong Zhang and Jun Zhang

Full text: PDF


Our goal of this paper is to provide a new method to construct the gyroscope random drift. Based on the State-space subspace system identification algorithm, the gyroscope random drift data are constructed to a series of scale gyroscope drift model to reduce the predict errors. The results of the experiment indicate that the gyroscope drift model constructed by State-space subspace system identification algorithm for the scale data low variance for the traditional method.
