Physical Parameter Estimation from State-Space Models for Systems with Missing Input Information

Luş, Hilmi

Abstract

In this article, the transformation of linear first-order models to second-order models is investigated for cases in which the system is excited by unknown inputs and ground excitations. It is shown that the second-order coefficients lie in the null space of a matrix, which is constructed from the partitions of the state matrix using the Kronecker product. The conditions that determine the size of this null space are discussed and solutions are developed for various cases.
