| Abstract: | The ITD time domain identification method was studied in this paper. The rule of theprevious time sampling was revised. A new method for determing the model confidence fac-tor has been proposed. All method have been proved through the computer simulation andapplicd to identify the vibrational mechanism of the continuous casting machine at the ironand steel company. |
