Functionality and limitations​

The beta-version of the app and toolbox contains a graphical user interface for analyzing structural properties of linear dynamic networks. On the basis of a given network topology, including the location of external excitaton signals and disturbances, tools are provided for the allocation of sensors (where to measure) and external signals (where to excite), for arriving at consistent estimates of either a full network or a single module.

The prime app-windows concern:

  • Loading, viewing and editing a network topology
  • Basic tests and operations on network topologies; node immersion
  • Analyzing and synthesizing module/network identifiability
  • Constructing predictor models (inputs and outputs) for local module identification.

The different technical operations are also available as individual m-files for command window operations.

The maximum network size that can be handled by the current implementation is around 50 nodes.

Future extensions​

In the near future the app/toolbox will be extended with data-manipulation and estimation algorithms so as to perform actual identification, and evaluate estimated network models.
