ITSIE (Interactive Tool for System Identification Education ) is a prototype tool for system identification education that has been developed in collaboration with Professor Sebastián Dormido  (Universidad Nacional de Educación a Distancia, UNED-Madrid) and Professors José Luis Guzmán Sanchez and Manuel Berenguel Soria from the University of Almería.  The tool illustrates in a novel way the interplay between experimental design, model structure selection, and validation in system identification, using both data and models from a series of representative dynamical systems.  The tool is a stand-along application and can be accessed from  A preprint of a paper describing the ITSIE tool presented at SYSID 2009 in St. Malo, France can be downloaded here.
