Multi-integral identification based on Feature-Data

To solve the parameters´ identification of Multi-Order system with pure delay unit, the algorithm based on the multiple integrations of the Feature-Data is presented. With the data of the stepping response, the System´s Feature-Data can be obtained according to the criterion of the Least-Square-Method and the minimum error of some parameters identified redundantly, and with the Multi-Integrations´ value of the feature-data, the equations are established, the parameters can be identified consequently.
