This paper introduced the stepwise regression analysis principle, grey correlation analysis and Kalman filter. Aiming at the situation of more impact factors on a certain dam deformation, a new algorithm for Kalman filter based on grey correlation analysis is given. It takes the horizontal deformation of a certain dam for example, through the grey correlation analysis to discuss the correlation degree of various impact factors and establish grey correlation Kalman filter model, and carry out comparison analysis of stepwise regression model. The results show that both two kinds of models have a better precision, but the grey relational Kalman filter presents higher synthesis accuracy and can provide more accurate prediction results. |
