A Control Theoretical Approach to Online Constrained Optimization
Umberto Casti, Nicola Bastianello, Ruggero Carli +1
In this paper we focus on the solution of online problems with time-varying, linear equality and inequality constraints. Our approach is to design a novel online algorithm by lever…
Internal Model-Based Online Optimization
Nicola Bastianello, Ruggero Carli, Sandro Zampieri
In this paper we propose a model-based approach to the design of online optimization algorithms, with the goal of improving the tracking of the solution trajectory (trajectories) w…
Brain Controllability: not a slam dunk yet
Samir Suweis, Chengyi Tu, Rodrigo P. Rocha +3
In our recent article (Tu et al., Warnings and caveats in brain controllability, arXiv:1705.08261) we provided quantitative evidence to show that there are warnings and caveats in…
Efficient Communication over Complex Dynamical Networks: The Role of Matrix Non-Normality
Giacomo Baggio, Virginia Rutten, Guillaume Hennequin +1
In both natural and engineered systems, communication often occurs dynamically over networks ranging from highly structured grids to largely disordered graphs. To use, or comprehen…
Warnings and Caveats in Brain Controllability
Chengyi Tu, Rodrigo P. Rocha, Maurizio Corbetta +3
In this work we challenge the main conclusions of Gu et al work (Controllability of structural brain networks. Nature communications 6, 8414, doi:10.1038/ncomms9414, 2015) on brain…
On the Dynamics of Deterministic Epidemic Propagation over Networks
Wenjun Mei, Shadi Mohagheghi, Sandro Zampieri +1
In this work we review a class of deterministic nonlinear models for the propagation of infectious diseases over contact networks with strongly-connected topologies. We consider ne…
On the Role of Network Centrality in the Controllability of Complex Networks
Nicoletta Bof, Giacomo Baggio, Sandro Zampieri
In recent years complex networks have gained increasing attention in different fields of science and engineering. The problem of controlling these networks is an interesting and ch…
On the existence and linear approximation of the power flow solution in power distribution networks
Saverio Bolognani, Sandro Zampieri
We consider the problem of deriving an explicit approximate solution of the nonlinear power equations that describe a balanced power distribution network. We give sufficient condit…
Controllability Metrics, Limitations and Algorithms for Complex Networks
Fabio Pasqualetti, Sandro Zampieri, Francesco Bullo
This paper studies the problem of controlling complex networks, that is, the joint problem of selecting a set of control nodes and of designing a control input to steer a network t…
Distributed reactive power feedback control for voltage regulation and loss minimization
Saverio Bolognani, Guido Cavraro, Ruggero Carli +1
We consider the problem of exploiting the microgenerators dispersed in the power distribution network in order to provide distributed reactive power compensation for power losses m…
A distributed control strategy for reactive power compensation in smart microgrids
Saverio Bolognani, Sandro Zampieri
We consider the problem of optimal reactive power compensation for the minimization of power distribution losses in a smart microgrid. We first propose an approximate model for the…
Gossip consensus algorithms via quantized communication
Ruggero Carli, Fabio Fagnani, Paolo Frasca +1
This paper considers the average consensus problem on a network of digital links, and proposes a set of algorithms based on pairwise ''gossip'' communications and updates. We study…
Efficient quantization for average consensus
Ruggero Carli, Fabio Fagnani, Paolo Frasca +1
This paper presents an algorithm which solves exponentially fast the average consensus problem on strongly connected network of digital links. The algorithm is based on an efficien…
Optimal strategies in the average consensus problem
Jean-Charles Delvenne, Ruggero Carli, Sandro Zampieri
We prove that for a set of communicating agents to compute the average of their initial positions (average consensus problem), the optimal topology of communication is given by a d…
