Abstract :
Based on temperature drift data of some micro-mechanical gyro, grey modeling research was carried out. Analyzing the essence of the traditional GM(1,1) model, and the logarithm transformation mathematic processing method was given for improving the smoothness of the primary data sequence and the approximate degree of the fitting equation. Then we built up a improved GM(1,1) model, compared with traditional GM(1,1) model, and it improves model accuracy. Further indicates model veracity and practice through error test, posteriori test and interrelated degree test.
