Differential coupling contributes to synchronization via a capacitor connection between chaotic circuits Regular Papers

Yu-meng XU, Zhao YAO, Aatef HOBINY, Jun MA

Frontiers of Information Technology & Electronic Engineering 2019, Volume 20, Issue 4, Pages 571-583 doi: 10.1631/FITEE.1800499

Abstract:

Nonlinear oscillators and circuits can be coupled to reach synchronization and consensus.The occurrence of complete synchronization means that all oscillators can maintain the same amplitudeHowever, phase synchronization means that the coupled oscillators just keep pace in oscillation even, and the energy flow of the controller is decreased when synchronization is realized.Cross coupling between different variables just triggers phase synchronization.

Blockchain in energy systems: values, opportunities, and limitations

Frontiers in Energy 2022, Volume 16, Issue 1, Pages 9-18 doi: 10.1007/s11708-022-0818-8

Abstract: The structure of a power energy system is becoming more distributed than before. It becomes challenging to manage such a system in a centralized way, because a central authority may not exist or may not be trusted by all parties. Blockchain is a promising tool to address this challenge, by enabling trusted collaboration in the absence of a trusted central authority. Its use in the energy sector has been pioneered by several pilot projects. However, to date the energy sector has not seen large-scale deployment of blockchain, partly because the founders of those pilot projects, the public, and utilities have not reached consensus on the values and limitations of blockchain in energy. This perspective aims to bridge this gap. First, the philosophy and unique values of blockchain are discussed. Second, some promising blockchain-based applications in energy systems are presented. Third, some common misunderstandings of blockchain in energy are discussed. Last, some frequently-asked questions from utilities are discussed. Hopefully this perspective can help advance large-scale deployment of blockchain in energy systems.

Frontiers of Information Technology & Electronic Engineering 2019, Volume 20, Issue 8, Pages 1026-1035 doi: 10.1631/FITEE.1800206

Abstract: In reality, bipedal robots are often required to perform gait transitions to achieve flexible walkingIn this paper, we consider the gait transition of a five-link underactuated three-dimensional (3D) bipedalupdated by an adaptive control law, and a transition controller that guides the robot from the current gaitto a neighboring point of the target gait so that the state trajectory can smoothly converge to thetarget gait.
