The operation of Fuel Cell Distributed Generation (FCDG) systems in distribution systems is introduced by modeling, controller design, and simulation study of a Solid Oxide Fuel Cell (SOFC) distributed generation (DG) system. The physical model of the fuel cell stack and dynamic models of power conditioning units are described. Then, suitable control architecture based on fuzzy logic contro...

Distributed systems are getting more and more popular in every field of computing. This is also true for reactive systems. Traditional techniques for developing reactive systems are not very suitable for developing distributed reactive systems, because they are based on synchrony hypothesis, and it can not be hold in a distributed system. It is necessary to develop new techniques to deal with d...

We introduce and study problems of distributed observation with bounded or unbounded memory. We are given a system modeled as a finite-word language L over some finite alphabet Σ and subalphabets Σ1, ...,Σn of Σ modeling n distinct observation points. We want to build (when there exist) n observers which collect projections of a behavior in L onto Σ1, ...,Σn, then send them to a central decisio...

We consider the Stable Marriage Problem and the Stable Roommates Problem, two well-known types of the general class of Stable Matching Problems. They are combinatorial problems which can be solved by centralized algorithms in polynomial time. This requires to make public lists of preferences which agents would like to keep private. With this aim, we define the distributed version of these probl...

This contribution describes the development and implementation of a novel software toolbox, NDOT, for the dynamic optimization (open loop optimal control) of nonlinear processes. This modular and flexible toolbox combines the control vector parameterization approach with a number of local and global nonlinear programming solvers and suitable dynamic simulation methods. NDOT is able to solve dyn...

in this paper, an adaptive fuzzy control scheme is proposed for a class of perturbed strict-feedback nonlinear systems with unknown discrete and distributed time-varying delays, and the proposed design method does not require a priori knowledge of the signs of the control gains.based on the backstepping technique, the adaptive fuzzy controller is constructed. the main contributions of the paper...
