Comment on `Detecting Topology Variations in Networks of Linear Dynamical Systems'

TL;DR

This paper critiques a recent study on detecting topology changes in linear dynamical networks, highlighting an error in the original detectability conditions through an illustrative example.

Contribution

It identifies and demonstrates an error in the existing network-theoretic conditions for topology variation detectability.

Findings

An example shows the error in the previous detectability conditions.

The paper emphasizes the need for revised conditions.

Highlights the importance of accurate theoretical conditions in network analysis.

Abstract

Conditions for the detectability of topology variations in dynamical networks are developed in a recent article in the IEEE Transactions on Control of Network Systems [1]. Here, an example is presented which illustrates an error in the network-theoretic conditions for detectability developed in [1].
