This paper considers a strongly connected network of agents, each capable of partially observing and controlling a discrete-time linear time-invariant (LTI) system that is jointly observable and controllable. Additionally, agents collaborate to achieve a shared estimated state, computed as the average of their local state estimates. Recent studies...
Smart grid technology drives economic and social development but raises vulnerability to cyber threats due to digital substations’ growing reliance. To counter these risks, recent updates to communication standards, including encryption and authentication processes, have been integrated into the infrastructure. Notably, adhering to the IEC 62351 st...
This paper introduces a distributed state estimation scheme for linear time-invariant (LTI) discrete-time systems, where observers, with partial observation of the system, communicate with each other over a directed and strongly connected (but not necessarily balanced) graph topology and execute a predefined number of average consensus steps in-bet...
Networked Control Systems (NCS) are pivotal for sectors like industrial automation, autonomous vehicles, and smart grids. However, merging communication networks with control loops brings complexities and security vulnerabilities, necessitating strong protection and authentication measures. This paper introduces an innovative Zero-Knowledge Proof (...
This paper introduces a novel fully distributed estimation scheme for nonlinear continuous-time dynamics over directed and strongly connected graphs. Leveraging on the assumption of local negativizability, the proposed approach performs the estimation of the interdependent subsystems of a cyber-physical system, despite the presence of nonlinear dep...
In this paper we focus our attention on an interesting property of linear and time-invariant systems, namely negativizability: a pair (A,C) is negativizable if a gain matrix K exists such that A-KC is negative definite. Notably, in this paper we show that negativizability can be a useful feature for solving distributed estimation and control proble...
Security of distributed consensus algorithms is rapidly becoming a matter of paramount importance. Existing approaches address it by identifying corrupted nodes and deleting them from the network, but this results in the permanent loss of the contribution of these agents even if they return to their proper functionality. In this paper, we consider...
Distributed cooperative multi-agent operations, which are emerging as effective solutions in countless application domains, are prone to eavesdropping by malicious entities due to their exposure on the network. Moreover, in several cases, agents are reluctant to disclose their initial conditions (even to legitimate neighbors) due to their sensitivi...
In this paper we consider a state estimation problem featuring an autonomous linear system and a set of interconnected sensors, each able to measure, in general, different measures and able to acquire their measurements and interact with each other in an asynchronous fashion.
In particular, as a first step in the solution of this problem, in this...
The greater availability and accessibility of IoT sensors, data acquisition systems and computer networks, led to the development of distributed control strategies aimed at monitoring and securing of Cyber-Physical Systems (CPS). In this paper, we propose a distributed asynchronous algorithm for the Secure State Reconstruction (SSR) which relies on...
Distributed average consensus is a fundamental feature of multi-agents systems; yet, in several cases agents are reluctant to disclose their initial conditions, e.g., due to their sensitivity about private data.
Consequently, ensuring the privacy of such information against honest but curious neighbours becomes a mandatory necessity. In this paper...
In this paper, we consider a distributed computation setting where agents are interconnected by a directed and strongly connected graph and the opinion of each agent is characterized by a convex set in a metric space. Given an initial point and under the assumption that the convex sets have a nonempty intersection, the aim of the agents is to compu...
In this paper we develop a simple, yet effective, secure communication protocol based on linear algebra that allows messages to be transmitted securely, without the need to encrypt them through computationally demanding approaches or to consider integer-valued plain messages, except during an initialization phase.
The scheme is composed by several...
The improvement of workers' safety, especially in complex and potentially dangerous scenario is a mandatory task. To this end, in recent years, there has been a large interest to complement actual passive solutions with IoT based system in order to provide a context related awareness information. Indeed, well informed workers can better manage anom...
