Abstract

The invention relates to a micro-electromechanical gyro information fusion system based on wavelet entropies and a micro-electromechanical gyro fusion method. The system comprises a micro-electromechanical gyro array module (1), a data preprocessing and statistical analysis module (2), a wavelet entropy analyzing and computing module (3) and a signal weighting fusion module (4) which are orderly connected, wherein the signal weighting fusion module (4) is further connected to the data preprocessing and statistical analysis module (2). The fusion method comprises the steps of: performing data preprocessing and statistical analysis on the signal of each micro-electromechanical gyro, and then performing wavelet entropy analysis and calculation, and finally performing signal weighting fusion so as to obtain a fused composite micro-electromechanical gyro signal. Compared with the common variance weighting method, the information fusion method provided by the invention has the advantages that the accuracy of the gyro output signal is improved, and the stability problem existing in a single system can be solved, so that the accuracy and the robustness of the micro-electromechanical gyro are improved effectively.

Description
