Abstract
The attempts to evaluate the synchronizability of chaotic systems have shown that additive periodic forcing, as a relevant source of stimuli, significantly impacts multiple forms of synchrony. This paper investigates the complete synchronizability of coupled periodically forced chaotic systems using the master stability function method. Three classic chaotic systems, Lorenz, Chen's, and Hindmarsh-Rose models are employed for this study. The numerical simulations supporting master stability function findings are also reported. The impacts of forcing amplitude and frequency on the critical value of coupling strength at which synchronization occurs are determined. Evidence implies that, as the stimulation is amplified, the chaotic forced systems tend to synchronize at weaker couplings than the autonomous versions. In contrast, high-frequency stimulation is entirely ineffective. The required forcing amplitude is also relative to the system's attractor size.
