Abstract

The expressions of matrix construction by using the singular value decomposition(SVD) are applied to the physics parameter identification of dynamic model.Then,based upon to the characteristics of a kind of matrix construction method,the orders of the parameter identification model can be reduced.After reducing,the mathematics and physics correspondence relations between the subsystem and the original system are distinct.the the condensation errors can be avoided.The numerical example shows the benefit of the presented methodology.
- dynamic model,
- parameter identification,
- inverse problem,
