Distributed design of deterministic discrete-time privacy preserving average consensus for multi-agent systems through network augmentation

Guilherme Ramos, A. Pedro Aguiar, Soummya Kar +1

Average consensus protocols emerge with a central role in distributed systems and decision-making such as distributed information fusion, distributed optimization, distributed esti…

Fractional cyber-neural systems -- a brief survey

Emily Reed, Sarthak Chatterjee, Guilherme Ramos +2

Neurotechnology has made great strides in the last 20 years. However, we still have a long way to go to commercialize many of these technologies as we lack a unified framework to s…

Minimum jointly structural input and output selection for strongly connected networks

Guilherme Ramos, A. Pedro Aguiar, Sérgio Pequito

In this paper, given a linear time-invariant strongly connected network, we study the problem of determining the minimum number of state variables that need to be simultaneously ac…

Minimum Structural Sensor Placement for Switched Linear Time-Invariant Systems and Unknown Inputs

Emily A. Reed, Guilherme Ramos, Paul Bogdan +1

In this paper, we study the structural state and input observability of continuous-time switched linear time-invariant systems and unknown inputs. First, we provide necessary and s…

A Discrete-time Reputation-based Resilient Consensus Algorithm for Synchronous or Asynchronous Communications

Guilherme Ramos, Daniel Silvestre, Carlos Silvestre

We tackle the problem of a set of agents achieving resilient consensus in the presence of attacked agents. We present a discrete-time reputation-based consensus algorithm for synch…

A scalable distributed dynamical systems approach to compute the strongly connected components and diameter of networks

Emily A. Reed, Guilherme Ramos, Paul Bogdan +1

Finding strongly connected components (SCCs) and the diameter of a directed network play a key role in a variety of discrete optimization problems, and subsequently, machine learni…

Structural Systems Theory: an overview of the last 15 years

Guilherme Ramos, A. Pedro Aguiar, Sergio Pequito

In this paper, we provide an overview of the research conducted in the context of structural systems since the latest survey by Dion et al. in 2003. We systematically consider all…

The Robust Minimal Controllability Problem

Sergio Pequito, Guilherme Ramos, Soummya Kar +2

In this paper, we address two minimal controllability problems, where the goal is to determine a minimal subset of state variables in a linear time-invariant system to be actuated…
