Position Sensorless Permanent Magnet Synchronous Machine Drives—A Review
IEEE transactions on industrial electronics (1982. Print), 2020Owing to the competitive advantages of cost reduction, system downsizing, and reliability enhancement, position sensorless control methods for permanent magnet synchronous machine drives have drawn increasing attention from academia to industrial ...

In this paper, a generalized droop control (GDC) is proposed for a grid-supporting inverter based on a comparison between traditional droop control and virtual synchronous generator (VSG) control.

Facilitating Synchronous Online Language Learning through Zoom
RELC Journal : A Journal of Language Teaching and Research in Southeast Asia, 2020Events caused by the COVID-19 pandemic have required second language (L2) educators to move away from face-to-face (F2F) lessons and adopt online teaching.

Transient Angle Stability of Virtual Synchronous Generators Using Lyapunov’s Direct Method
IEEE Transactions on Smart Grid, 2019With an increasing number of distributed energy resources integrated into the power system, inverters need to take on the corresponding responsibility for the security and stability of the system.

On-Line Inertia Estimation for Synchronous and Non-Synchronous Devices
IEEE Transactions on Power Systems, 2021This paper proposes an on-line estimation method able to track the inertia of synchronous machines as well as the equivalent, possibly time-varying inertia from the converter-interfaced generators.

With the development of virtual synchronous generator (VSG) techniques, parallel operations of synchronous generators (SGs) and VSGs become increasingly common in a microgrid. The differences between paralleled systems will affect the transient stability

International Journal of Bifurcation and Chaos, 2010
In this work we study the synchronization between identical pairs of hyperchaotic mathematical systems symmetrically coupled. Calculations are performed firstly in two well-known hyperchaotic systems, and then compared with the results obtained coupling symmetrically two Takens–Bogdanov systems (TBS) which represent a bifurcation in Codimension 2 (a ...

Science, Technology, & Human Values, 2017
Sociological studies of work and time have argued that academic temporalities are increasingly rationalized and rendered accountable, resulting in a divergence of planned and experienced time in academic work. Shared research facilities that provide platform technologies to large user pools are no exception to this, as its administrations seek to ...

Science, 1966
A method using the standard radio-frequency receiver was developed to telemeter biopotentials across the intact body wall; it can be employed to program a stimulus to the heart at any phase of the cardiac cycle. The small variations of potential across the electrodes of the implanted cardiac pacemaker change the natural resonant frequency of the ...

Journal of Dynamical Systems and Geometric Theories, 2007
In this paper, we use nonlinear control method for synchronization of two identical chaotic generalized Lotka-Volterra system. The determination of the controller is based on the Lyapunov stability theory. Numerical simulation results are shown for demonstration.
