Synchronization in Three Coupled van der Pol Oscillators with Different Memristor Coupling Strengths

Abstract

We developed three coupled van der Pol oscillators with different memristor coupling strengths. We investigate the synchronization state changing the coupling strength of one memristor. Compared with different resistor coupling strengths, amplitude death as the new synchronization state is obtained. In addition, we evaluated the synchronization dependence on the parameter of one memristor to analyze the relative phase difference, amplitude, and power consumption.
