Deformation Prediction Modal Combined with Calman and AR Algorithm
Kaifeng Ma · Journal of Irrigation and Drainage · 2008
The non-stationary time series data were dealt with the hybrid algorithm modal which combining the combined Calman and AR algorithm,and the modal was build,in which the state equations was set with the parameters of stochastic variance of the AR modal instead of extracting the tendency items from the original data in conventional AR modals,and measure equations were constructed with the observation data,then the AR modal can be solved by the Calman algorithm.The deformation prediction results of the modal used in water transportation tunnel construction showed that this method was accuracy and feasible.
