Title: Positive Realness of a Transfer Function Neither Implies Nor is Implied by the External Positivity of their Associate Realizations
Authors: M. De la Sen
Categories: math.OC Optimization and Control
Comments: 5 pages

Abstract: This letter discusses the differences between the properties of positive realness of transfer functions and external positivity in linear time-invariant dynamic systems. It is proved that each one of both properties does not imply to each other.
