Dynamics of Coupled Chaotic Bonhoeffer – van der Pol Oscillators
Authors: , , ,
Abstract: In the present paper, we have studied the dynamics of coupled chaotic Bonhoeffer – van der Pol (BvP) electrical oscillators. In the case of series connection and bidirectional coupling via linear resistor, as the coupling strength varies, the chaotic states are driven to periodic states. In the case of ring-type connection, synchronization is observed in the case that the voltage driven BvP oscillator have different circuit parameters than the two identical current-driven BvP oscillators. The Bonhoeffer – van der Pol (BvP) electrical nonlinear oscillators simulate neuron cells and in this case the linear coupling resistors act as electric synapses. These synapses varying their resistance control the dynamics of the neuron cells, from chaotic to periodic states.
