In this paper, we discuss a distributed control architecture, aimed at networks with linear and time-invariant dynamics, which is amenable to convex formulations for controller design. The proposed approach well suited large scale systems, since the resulting feedback schemes completely avoid exchange of internal states, i.e., plant or among sub-controllers. Additionally, provide state-space fo...

Today we experience an ongoing expansion of the range available information, advanced communication technologies, and increase in multitasking. This has resulted a distributed nature cognitive activity, where external resources, devices other people are involved. That’s why development metacognitive knowledge strategies is crucial for effective usage one’s own abilities, as well cultural techno...

AltstmctThe purpose of this paper is to develop methods to reduce the complexity of nonlinear distributed systems by using symmetry propers within the system. A method for contracting and expanding controllable nonlinear systems is developed which maintains the controllability of the original system. In fact, it is shown that an entire equivalence class of symmetric nonlinear distributed contro...

The Hierarchical Interface-Based Supervisory Control (HISC) framework was proposed to address challenges inherent in modeling the behavior of large, complex systems. Such systems are often characterized by decentralized or distributed architectures, where agents have only a partial view of the system behavior and cooperate to achieve the control objective, aspects unsupported by HISC. We introd...

In order to increase availability in a distributed system some or all of the data items are replicated and stored at separate sites. This is an issue of key concern especially since there is such a proliferation of wireless technologies and mobile users. However, the concurrent processing of transactions at separate sites can generate inconsistencies in the stored information. We have built a d...

The European project Crisys" aims at improving and formalizing the actual methods, techniques and tools used in the industries concerned with process control, in order to support a global system approach when developing Distributed Control System. This paper focuses on the main result of the Crisys project: the quasi-synchronous approach which is based on the synchronous language Lustre-Scade. ...
