A non-autonomous memristor circuit based on van der Pol oscillator with double periodically forcing term is presented and discussed. Firstly, the differences of oscillation model between Euler method symplectic method, four-order Runge–Kutta (RK4) Runge–Kutta–Nyström (SRKN4), RK4 SRKN4 in preserving structure are compared from theoretical numerical simulations, symmetry stability scheme demonstrated. Moreover, analytic solution primary subharmonic simultaneous resonance this system obtained by using multi-scale method. Finally, relation system, chaotic dynamics behaviors different parameters studied.

Chaotic Circuit Using a Ring Oscillator and a van der Pol Oscillator
In this study, we propose a chaotic circuit using a ring oscillator and a van der Pol oscillator. The structure of this circuit is very simple.

متن کاملNonlinear Circuit Analysis in Time and Frequency-domain Example: The Forced Van-der-Pol Oscillator
To predict nonlinear circuit behaviour, harmonic-balance (HB) is a popular and useful frequency-domain technique. But given its mathematical nature, it can only converge to mathematical solutions being harmonically related to the input sources into the circuit. Nevertheless, the mathematical solutions to a nonlinear system do not necessarily need to be harmonically related to the input signals ...

Phase noise is the most important parameter in many oscillators. The proposed method in this paper is based on nonlinear stochastic differential equation for phase noise analysis approach. The influences of two different sources of noise in the Van Der Pol oscillator adopted this method are compared. The source of noise is a white noise process which is a genuinely stochastic process and the ot...

We calculated Eq. (4) by using the Runge-Kutta method. The attractors obtained by the simulations are shown in Fig. 3(a). We can confirm the generation of periodic and chaotic attractors.

We can see tha...
متن کاملPhase Model for the relaxed van der Pol oscillator and its application to synchronization analysis
A one dimensional phase model for the classic two dimensional van der Pol oscillator is developed. This model is restricted to the relaxed case, and its construction is based on the slow and fast transitions the phase goes through during its cycle. An application of the phase model is included in which synchronization of two coupled van der Pol oscillators is analyzed and even used to calculate...
