Synchronization of chemical systems using external forcing

We report the synchronization of dynamics in a numerical model simulating electrochemical corrosion using external chaotic forcing, periodic forcing, and finally forcing including a random component (random forcing). For all three external forcings synchronization is achieved when the two response systems are at identical parameter conditions exhibiting similar behavior. However when the two response systems are at unequal parameter values exhibiting different dynamical behavior, synchronization is achieved only for forcing including a random variable (random forcing). This ability of random perturbations to achieve generalized synchronization makes it a candidate worthy of consideration in problems involving synchronization of nonidentical systems.
