Suppressing synchrony in an array of the modified FitzHugh–Nagumo oscillators by filtering the mean field

A control method for desynchronizing an array of N mean-field coupled modified FitzHugh–Nagumo oscillators is described. The technique is based on filtering the mean field sampled at the coupling node. The first order branched RC filter is composed of N coupling resistors and a single capacitor. The technique can be applied to arrays in a wide range of coupling strength (in general, unknown strength) between the individual oscillators. Both numerical simulations and hardware experiments with an electrical circuit imitating dynamics of the model have been performed.
