Control and signal processing for two dimensional systems in web forming industries

Considers two dimensional control and signal processing as they occur in manufacturing industries. There are a number of related reasons for studying this area and presenting the collected results. To begin with, two dimensional control and signal processing is an area of systems research which is of theoretical and practical relevance. The theoretical importance flows from the special technical properties of two dimensional dynamical systems. From a practical point it is necessary to research and develop two dimensional control and signal processing because a wide class of industrial processes have two dimensional features. Important among these is the class of systems considered here, namely web forming manufacturing processes.
