Inversion and Tracking Problems for Time Delay Linear Systems

Delay differential systems play a basic role in modelling phenomena which involve transportation over non negligible distances of materials, as it happens in many industrial processes, or of information, as it happens in large communication systems. Various approaches for different problems have been developed (see [2], [13], [14] for a general introduction to this topic and the Proceedings of the IFAC Workshops on Time Delay Systems (1998, 2000, 2001, 2003) for an account of the most recent research activity).
