✦ Synopsis

In a previous work an approach was presentedfor extracting information about the eiyenvalues of a linear, time-invariant dynamic system directly from a graphical model. In this paper a generalization is given of the results previously obtained. For some particular cases we can give the entire spectrum. For these cases the spectrum is shown as afunction of the structure of an abstract form of the bond graph model. For more general cases, we give upper limits on the imaginery part, and upper and lower limits on the real parts, of the eigenvalues. In contrast to most existing methods, the information about the eigenvalues is generated prior to deriving the state equations. When suitably automated, the results obtained here can provide a considerable reduction in the computational effort required to get information about eigenvalues. Thisfeature is particularly useful in an interactive design context.

## In this paper, a model reduction technique to remedy the singularity of reduced- order models is proposed. The approach adopted is based on the least-square fitting of timemoments of the system. The proposed method is also auailable to stabilize unstable reduced models. This method is superior t
