Van der Pol oscillator

[′van dər ‚pōl ‚äs·ə‚lād·ər]
(electronics)
A type of relaxation oscillator which has a single pentode tube and an external circuit with a capacitance that causes the device to switch between two values of the screen voltage.
(physics)
A vibrating system that is governed by an equation of the form + ε(-x + ⅓ x 3) + x = 0.

Two continuous-time systems are used as case study for the aPBC--the forced van der Pol oscillator and Rossler system.
Forced van der Pol Oscillator. The forced van der Pol (vdP) oscillator is described by the nonlinear state space model (28):
On the other hand, it can be seen that for [epsilon] = 0.1 the motion of the Van Der Pol oscillator is very nearly harmonic, exhibiting alternate compression and rarefaction of the density with a relatively small period [PHI] of about 6.3 [micro]s.

The Van der Pol oscillator is a self-maintained electrical circuit made up of an Inductor (L), a capacitor initially charged with a capacitance (C) and a non-linear resistance (R); all of them connected in series as indicated in Fig.

They include recurrence quantification analysis of bipolar disorder performed using a Van der Pol oscillator model, detecting low-dimensional chaos in small noisy sample sets, Alan Turing meets the Sphinx, fractal geometry in computer graphics and in virtual reality, buyer decisions in the US housing industry, secular variation in the climatic memory of five Italian deep lakes, and in everyday action notes for a mindscape of bioethics.
As a simple example, PLR can qualitatively analyze the behavior of an undriven van der Pol oscillator, a simple nonlinear circuit consisting of a capacitor, an inductor, and a nonlinear resistor connected in series.
They found small traveling waves through the system support that lock the phase difference among all metronomes and they model the connections in terms of a Van der Pol oscillator. Aragones and Guasch [6] presented a theoretical analysis of path propagation in a set of systems with similar structures.
