Analog circuits for modeling and controlling synchrony in arrays of coupled oscillators

Abstract

An analog technique for desynchronisation of FitzHugh-Nagumo type oscillators is described. Two-terminal feedback controller is applied to the network. The controller nullifies the voltage at the coupling node and effectively decouples the individual oscillators. Both, numerical simulations and hardware experiments are performed. The results for array of 30 coupled FitzHugh-Nagumo oscillators are presented.
