Abstract: In the average consensus a set of linear systems has to be driven to the same final state which corresponds to the average of their initial states. This contribution presents a consensus strategy in which the systems can exchange information among themselves according to a fixed connected digital communication network. Beside the decentralized computational aspects induced by the choice of the communication network, we here have also to face the quantization effects due to the digital links. We here present and discuss two different encoding/decoding strategies with theoretical and simulation results on their performance.

Francesco Bullo,Jorge E. Cortes,Sonia Martinez +2 more
- 26 Jul 2009
TL;DR: This self-contained introduction to the distributed control of robotic networks offers a broad set of tools for understanding coordination algorithms, determining their correctness, and assessing their complexity; and it analyzes various cooperative strategies for tasks such as consensus, rendezvous, connectivity maintenance, deployment, and boundary estimation.
Consensus of Multi-Agent Systems With General Linear and Lipschitz Nonlinear Dynamics Using Distributed Adaptive Protocols
TL;DR: This technical brief considers the distributed consensus problems for multi-agent systems with general linear and Lipschitz nonlinear dynamics and finds that the adaptive consensus protocols here can be implemented by each agent in a fully distributed fashion without using any global information.

Distributed consensus of linear multi-agent systems with adaptive dynamic protocols
TL;DR: This paper considers the distributed consensus problem of multi-agent systems with general continuous-time linear dynamics for both the cases without and with a leader whose control input might be nonzero and time varying, and proposes two types of distributed adaptive dynamic consensus protocols.
Network Topology and Communication Data Rate for Consensusability of Discrete-Time Multi-Agent Systems
Keyou You,Lihua Xie +1 more
TL;DR: In this article, a necessary and sufficient condition for consensusability under a common control protocol is given, which explicitly reveals how the intrinsic entropy rate of the agent dynamic and the communication graph jointly affect consensusability.

- 01 Feb 2009
TL;DR: In this paper, the convergence speed of distributed iterative algorithms for the consensus and averaging problems was studied, with emphasis on the latter problem, and lower bounds on the worst-case convergence time for various classes of linear, time-invariant, distributed consensus methods were established.

Stabilization of linear systems with limited information
Nicola Elia,Sanjoy K. Mitter +1 more
TL;DR: By relaxing the definition of quadratic stability, it is shown how to construct logarithmic quantizers with only finite number of quantization levels and still achieve practical stability of the closed-loop system.
A scheme for robust distributed sensor fusion based on average consensus
Lin Xiao,Stephen Boyd,Sanjay Lall +2 more
- 24 Apr 2005
TL;DR: This work proposes a simple distributed iterative scheme, based on distributed average consensus in the network, to compute the maximum-likelihood estimate of the parameters, and shows that it works in a network with dynamically changing topology, provided that the infinitely occurring communication graphs are jointly connected.
Distributed average consensus with least-mean-square deviation
TL;DR: The problem of finding the (symmetric) edge weights that result in the least mean-square deviation in steady state is considered and it is shown that this problem can be cast as a convex optimization problem, so the global solution can be found efficiently.

Feedback Control Under Data Rate Constraints: An Overview

- 05 Mar 2007
TL;DR: In this article, the authors review the results available in the literature on data-rate-limited control for linear systems and show how fundamental tradeoffs between the data rate and control goals, such as stability, mean entry times, and asymptotic state norms, emerge naturally.
