    European Research Network System Identification (ERNSI)

    This network was created in 1991, before the ERCIM WG-CST was created. Of the nine research teams of ERNSI, five are also teams of the ERCIM WG-CST. Of the eight research teams of the ERCIM WG-CST three are not teams of ERNSI. The coordinator of ERNSI is also the Chair of the Steering Committee of the ERCIM WG-CST.

    A.7 Project Description

    Research Objectives

    The project objectives are: The research objectives are to produce algorithms and theory for the following topics of system identification:

    Methodological Approach and Workplan

    The problem of system identification is to obtain a mathematical model for a phenomenon from data. The purpose of the model may be engineering analysis, simulation, monitoring, forecasting or prediction, or control. System identification proceeds by the steps:
    1. Selection of a model class based on a priori knowledge, on the objective, and on data;
    2. Input design, experimentation, and data collection;
    3. Parameterization of the model class based on realization theory and identifiability;
    4. Approximation, selection of an element in the model class that best approximates the data;
    5. Evaluation of the quality of the selected model with respect to the objective.
    In this project attention is focused on modeling, realization, and structure theory, corresponding to the steps (1) and (3) of the procedure, as well as on approximation and evaluation, corresponding to the steps (4) and (5).

    Section F: Cooperation with Commercial Companies and Public Services

     The ERCIM WG-CST does not have direct relations with commercial companies or public services as a working group. The individual teams have contacts with industry that are not all known to the Chairman of the Steering Committee.

    For the related ERNSI network, at the ERNSI Workshops System Identification speakers from commercial companies or from public services are invited.

    1. Dr. K. Stahl (Saab AB), Applications of system identification in the aerospace industry,
      an invited lecture at the ERNSI Workshop System Identification 2000, Vadstena, Sweden.
    2. Dr. Christine Zanchi (CNES, Toulouse), Identification and modeling of satellite equipment.
      at the ERNSI Workshop System Identification 1999, Theoule, France.
    3. Dr. P. Steyer (INRA, Narbonne), Waste water treatment-practical modeling
      at the ERNSI Workshop System Identification 1999, Theoule, France.

    Section G: Comments
    1. The team members of the ERCIM WG-CST regard research cooperation in a European network as very useful for their research.
    2. The Steering Committee of the ERCIM WG-CST is of the opinion that the functioning of the Working Group within ERCIM will stay at a relatively low level because about half of the groups also participate in another European wide project.
    3. Financial support for the travel and subsistence costs of team members of the ERCIM WG-CST for their participation in the ERCIM Workshops Systems and Control will reinforce the cooperation.
