Decentralized Control Design Using a New Approach of Longitudinal Multi-overlapping Decomposition Strategy: Application to Web Winding System

Industrial systems are generally characterized by their complication which is essentially caused by the large number of variables exist in such systems, and also the overlapping structure of information coming to or going from it. This complication can afford loss of some important parts of information, in addition to making study of these systems, if not impossible, at least very hard for researchers. Many researchers discuss the development of techniques to profit the structure of the system under study in order to reduce control complications. The aim of this paper is to use a proposed longitudinal approach to multi-overlapping controller design of large scale industrial systems; this approach permits us to show the advantages of multi-overlapping decomposition strategy and its application in order to have a more robust controller. Thus, it leads to more computational efficient design strategy that is well suited for large scale applications. A multi-overlapping web winding system with longitudinal structure is presented to illustrate the effectiveness of the proposed design.
