| Abstract: | The parameter estimation and system identification of nonlinear structures is a subject which serves to obtain and verify mathematical model of nonlinear structures. This paper summarizes the development of the parameter estimation and system identification of nonlinear structures in the world. All kinds of mathematical model of nonlinear structures, parameter estimation methods of single-degree and multiple-degree freedom (SDF MDF) nonlinear system and non-parametric identification methods are introduced systematically. |
