In this paper we investigate the sine qua non condition of existence of equilibria for electrical systems with external sources furnishing constant power to the loads, which is a scenario encountered in modern applications. ...

In this paper the problem of robust coordination of multi–agent systems via energy–shaping is studied. The agents are nonidentical, Euler–Lagrange systems with uncertain parameters. The control objective is to drive all ...

In this article we consider the objective of efficient transfer of electric energy between subsystems, where each subsystem can generate, store, or consume energy.

Dans de nombreux r eseaux, la r egulation e cace du transfert d' energie entre les sous-syst emes de production, de stockage et d'utilisation demeure un sujet di cile a traiter. Les auteurs proposent ici une nouvelle ...

The problem of existence and stability of equilibria of linear systems with constant power loads is addressed in this paper. First, we correct an unfortunate mistake in our recent paper [10] pertaining to the sufficiency ...

This paper addresses the problem of stable bilateral teleoperation, through a time-delayed communication channel, for a n-DOF system without position drift. The classical wave variables-based scheme encodes velocity and ...

This paper presents two versions of adaptive controllers for nonlinear bilateral teleoperators, each providing asymptotic convergence of velocity and position errors to zero, independent of constant time-delays. Moreover, ...

We consider a doubly–fed induction machine controlled through the rotor voltage and connected to a variable local load—that acts as an energy–switching device between a local prime mover (a flywheel) and the electrical ...

This article advances an analysis and compensator design framework for power-factor compensation based on cyclodissipativity. Although the framework applies to general polyphase unbalanced circuits, this paper have focused ...
