Hub-enhanced noise-sustained synchronization of an externally forced FitzHugh–Nagumo ring
(Elsevier Science, 2017-02)
A ring of FitzHugh–Nagumo units with antiphase coupling between their activator fields and submitted to a adiabatic harmonic subthreshold signal, is in turn globally coupled in electrical mode with the activator field of ...
Synchronization of chemical noise-sustained structures in asymmetrically coupled differential-flow reactors
(American Physical Society, 2013-12)
The differential-flow-induced chemical instability is investigated in the context of two coupled reactors with cubic autocatalytic kinetics (the Gray-Scott model). Previous results for master-slave arrangement [Izús, Deza, ...
On the control of vibrations using synchrophasing
(2013-09-30)
This paper describes the application of a technique, known as synchrophasing, to the control of machinery vibration. It is applicable to machinery installations, in which several synchronous machines, such as those driven ...
High order sliding mode controllers and differentiators for a synchronous generator with exciter dynamics
(2005)
The problem of angular velocity of rotor and voltage control in synchronous generator machines is considered. As a robust solution of this problem the block control technique with sliding mode is proposed. The physical ...
Controle por modos deslizantes e observador de distúrbios aplicados ao motor síncrono de ímãs permanentes
(Universidade Federal de Santa MariaBREngenharia ElétricaUFSMPrograma de Pós-Graduação em Engenharia Elétrica, 2015-08-20)
This master thesis proposes a current control technique based on sliding mode strategy
and disturbance observer for high-performance drive applied to permanent magnet
synchronous motors and can be extended to other ...
Collective modes of coupled phase oscillators with delayed coupling
(American Physical Society, 2012-04)
We study the effects of delayed coupling on timing and pattern formation in spatially extended systems of dynamic oscillators. Starting from a discrete lattice of coupled oscillators, we derive a generic continuum theory ...
On the synchronization of two metronomes and their related dynamics
(2016-10-03)
Synchronization was first reported by Christiaan Huygens in 1665 when he observed anti-phase synchronization achieved by two pendulum clocks hanging on a common base. Since then researchers have tried to understand the ...
Fluorescent fingerprints of edible oils and biodiesel by means total synchronous fluorescence and Tucker3 modeling
(Pergamon-Elsevier Science Ltd, 2017-03)
The present work proposes the use of total synchronous fluorescence spectroscopy (TSFS) as a discrimination methodology for fluorescent compounds in edible oils, which are preserved after the transesterification processes ...
Dynamics of mobile coupled phase oscillators
(American Physical Society, 2013-03-21)
We study the transient synchronization dynamics of locally coupled phase oscillators moving on a one-dimensional lattice. Analysis of spatial phase correlation shows that mobility speeds up relaxation of spatial modes and ...
