A multi-agent system design-methodology is used to address the highly dynamic, regulated, complex, distributed environment of interconnected services. A framework of three interconnected levels is applied to tackle this issue relying on coordination and organisational techniques, as well as on Web-services and new methodologies to design, deploy and maintain a distributed system. This paper pre...

This paper investigates the problem of the stabilization of a system (A, Bd) consisting of two interconnected subsystems, with decentralized state or output feedback. Following the initial definition of the global system and of its two subsystems in the state-space, and based on the intercontrollability matrix D(s) of system (A, Bd) and on the kernel U(s) of D(s), an equivalent system {M(s), I2...

Recent results by the authors have shown how to construct a class of structured controllers for large scale spatially interconnected systems via linear matrix inequalities. Of paramount importance in the control of interconnected systems is that the controlled system be stable when arbitrarily small communication delays are present between subsystems. In this paper, it is shown how to realize t...

Decentralized overlapping feedback laws are designed for a formation of unmanned aerial vehicles. The dynamic model of the formation with an overlapping information structure constraint is treated as an interconnected system with overlapping subsystems. Using the mathematical framework of the inclusion principle, the interconnected system is expanded into a higher dimensional space in which the...

This paper presents an analysis on dynamic performance of a three-area thermal system interconnected with HVDC links when subjected to parametric uncertainties. In this paper all the three areas consists of thermal power plants. The HVDC link is used as a system interconnection between all the three areas. Open transmission access and the evolution of more socialised companies for generation, t...

In this paper fuzzy controllers are designed for FACTS devices in interconnected power systems. Two typical FACTS devices, STATCOM and UPFC, are used as examples to show that FACTS devices with well designed fuzzy controllers can improve interconnected power system dynamic behavior significantly.
