Abstract :
In this paper the definition of the σ-reciprocal system is introduced. This allow one to show that the generalized singular perturbation approximation method for model reduction is related to the direct truncation of the σ-reciprocal system. Based on this definition two new model order reduction algorithms are presented. The suitability of the proposed reduction methods is illustrated by means of two numerical examples
