چکیده
In this study, synchronization phenomena observed from coupled van der Pol oscillators involving periodically forced capacitors are investigated. Firstly, we confirm effects of parametric excitation on synchronization. Next, we investigate behavior of parametric excitation in coupled system. By carrying out computer calculations for two to five subcircuits cases, various interesting synchronization phenomena of chaos are confirmed.

Synchronization Phenomena in van der Pol oscillators Coupled by a Time-Varying resistor
In this study, synchronization phenomena observed in van der Pol oscillators coupled by a timevarying resistor are investigated. We realize the time-varying resistor by switching a positive and a negative resistor periodically. By carrying out circuit experiments and computer calculations, interesting synchronization phenomena can be confirmed to be generated in this system. Namely, the synchro...
متن کاملQuantum synchronization of two Van der Pol oscillators
We study synchronization of two dissipatively coupled Van der Pol oscillators in the quantum regime. Due to quantum noise strict frequency locking is absent and is replaced by a crossover from weak to strong frequency entrainment. We discuss the differences to the behavior of one quantum Van der Pol oscillator subject to an external drive. Moreover, we describe a possible experimental realizati...

Abstract— In this study, synchronization phenomena observed in van der Pol oscillators coupled by a fifth-power nonlinear resistor are investigated. By carrying out computer simulations, interesting synchronization phenomena can be confirmed to be generated in this system. Namely, the synchronization states change according to the coupling strength and nonlinearity of the coupling resistor.
متن کاملBistable Phase Synchronization and Chaos in a System of Coupled Van Der Pol Duffing Oscillators
Analysis of numerical solutions for a system of two van der Pol–Duffing oscillators with nonlinear coupling showed that there exist chaotic switchings (occurring at irregular time intervals) between two oscillatory regimes differing by nearly time-constant phase shifts between the coupled subsystems. The analysis includes the investigation of bifurcations of the periodic motions corresponding t...
متن کاملSynchronous regimes in ensembles of coupled Bonhoeffer-van der Pol oscillators.
We study synchronous behavior in ensembles of locally coupled nonidentical Bonhoeffer-van der Pol oscillators. We show that, in a chain of N elements not less than 2;{N-1}, different coexisting regimes of global synchronization are possible, and we investigate wave-induced synchronous regimes in a chain and in a lattice of coupled nonidentical Bonhoeffer-van der Pol oscillators.
