✦ Synopsis

Based on singular perturbations concepts, an iterative method for separation of time scales removes inconsistencies of the classical quasi-steady-state approach, and it systematically improves the accuracy of lower order models.

The singular perturbation method applied to multi-time scale processes enables the reduction of dimensionality by considering only one part of the system-the slow or the fast part-depending on thefrequency domain of interest. Thefast and slow dynamics of bond graph models can be estimated by determi

## Abstract This paper presents an examination of the methods for the iterative modal perturbation and the application of these methods to the reanalysis of the eigenvalue problem. The iteration is based on the first‐order modal perturbation. In two examples, it is shown that the iterative analysis
