Temperature drift modeling and compensation of micro-electro-mechanical system gyroscope based on improved support vector machine algorithms

This article suggested two methods to compensate for the temperature drift of the micro-electro-mechanical system gyroscopes, which are support vector machine method and C-means support vector machine. The output of X axis which was ranged from -40 degrees C to 60 degrees C based on the micro-electro-mechanical system gyroscope is reduced and analyzed in this article. The results showed the correctness of the two methods. The final results indicate that when the temperature is ranged from -40 degrees C to 60 degrees C, the factor of B is reduced from 0.424 (degrees h) to 0.02194 (degrees h), and when the temperature is ranged from 60 degrees C to -40 degrees C, the factor of B is reduced from 0.1056 (degrees h) to 0.0329 (degrees h), and the temperature drift trend and noise characteristics are improved clearly.
