Synchronization properties of self-sustained mechanical oscillators
(Amer Physical Soc, 2013-03)
We study, both analytically and numerically, the dynamics of mechanical oscillators kept in motion by a feedback force, which is generated electronically from a signal produced by the oscillators themselves. This kind of ...
Self-sustained oscillations with delayed velocity feedback
(Instituto de Física de Líquidos y Sistemas Biológicos, 2017-03-30)
We study a model for a nonlinear mechanical oscillator, relevant to the dynamics of micro- and nanomechanical time-keeping devices, where periodic motion is sustained by a feedback force proportional to the oscillation ...
On numerical simulations of a nonlinear self-excited system with two non-ideal sources
(2005-12-01)
In this work, the dynamic behavior of self-synchronization and synchronization through mechanical interactions between the nonlinear self-excited oscillating system and two non-ideal sources are examined by numerical ...

Self-Sustained Micromechanical Oscillator with Linear Feedback
(American Physical Society, 2016-07)
Autonomous oscillators, such as clocks and lasers, produce periodic signals without any external frequency reference. In order to sustain stable periodic motion, there needs to be an external energy supply as well as ...
Symmetry breaking, Josephson oscillation and self-trapping in a self-bound three-dimensional quantum ball
(2017-12-01)
We study spontaneous symmetry breaking (SSB), Josephson oscillation, and self-trapping in a stable, mobile, three-dimensional matter-wave spherical quantum ball self-bound by attractive two-body and repulsive three-body ...
Stick-slip chaos in a non-ideal self-excited system
(2003-12-01)
In engineering practical systems the excitation source is generally dependent on the system dynamic structure. In this paper we analyze a self-excited oscillating system due to dry friction which interacts with an energy ...

Complex dynamic behaviors in a new Colpitts oscillator topology based on a voltage comparator
(2020-03-01)
Designing simple chaotic circuits with complex dynamic behaviors that can generate coexisting and hidden attractors has attracted much interest recently. In this paper, a new voltage-tunable Colpitts oscillator based on a ...
Frequency stabilization in nonlinear micromechanical oscillators
(Springer, 2012-01)
Mechanical oscillators are present in almost every electronic device. They mainly consist of a resonating element providing an oscillating output with a specific frequency. Their ability to maintain a determined frequency ...
