Blockchain: What Does It Mean to Industrial Electronics?: Technologies, Challenges, and Opportunities

Imagine you want to send money to a friend overseas. Wouldn't it be good if you didn't have to pay hefty fees to the intermediaries, and your friend received the funds very quickly? Now imagine ordering parts to make a product in your manufacturing plant. Wouldn't it be great if you were able to verify where each part comes from and have...

A Separation-Based Methodology to Consensus Tracking of Switched High-Order Nonlinear Multiagent Systems

This work investigates a reduced-complexity adaptive methodology to consensus tracking for a team of uncertain high-order nonlinear systems with switched (possibly asynchronous) dynamics. It is well known that high-order nonlinear systems are intrinsically challenging as feedback linearization and backstepping methods successfully developed...

Distributed Time-Varying Optimization of Second-Order Multiagent Systems Under Limited Interaction Ranges

This article investigates the distributed time-varying optimization problem for second-order multiagent systems (MASs) under limited interaction ranges. The goal is to seek the minimum of the sum of local time-varying cost functions (CFs), where each CF is only available to the corresponding agent. Limited communication range refers to the...

DAMYSUS: Streamlined BFT Consensus Leveraging Trusted Components

Recently, streamlined Byzantine Fault Tolerant (BFT) consensus protocols, such as HotStuff, have been proposed as a means to circumvent the inefficient view-changes of traditional BFT protocols, such as PBFT. Several works have detailed trusted components, and BFT protocols that leverage them to tolerate a minority of faulty nodes and use a...

Consensus in high-power multiagent systems with mixed unknown control directions via hybrid Nussbaum-based control

This work investigates the consensus tracking problem for high-power nonlinear multiagent systems with partially unknown control directions. The main challenge of considering such dynamics lies in the fact that their linearized dynamics contain uncontrollable modes, making the standard backstepping technique fail; also, the presence of mixed...
