A two-level structural model for large scale systems
In this paper, a class of two-level systems is considered where N-linear subsystems S-1, S-2,...S-N in a lower hierarchical level are interconnected through a coordinator So in a higher hierarchical level. The model of such a system is presented together with a controlling algorithm that preserves the structure of the system. The paper is mainly a survey of all related work and presents all the aspects of such a controlling scheme such as structural controllability, fixed modes, the algorithm itself and stability of the closed loop system. A generic system functionalization architecture which can utilize advanced Information Technologies (IT) is proposed. (C) 1998 Elsevier Science B.V. All rights reserved.
