Abstract

In this paper, we explore the inducement of synchronization by transient uncoupling observed in unidirectionally coupled chaotic systems with inherent frequency parameters. The emergence of desyncronization with increase in frequency factor for fixed values of coupling strength and the suppression of stable synchronization to lower values of coupling strength in the presence of frequency factors are identified. The inducement of complete synchronization using the method of transient uncoupling in coupled Rössler systems and Chua’s circuit systems with frequency parameters incorporated in their system equations is reported. The enhancement of synchronization stability over greater values of coupling strength and frequency factors on the introduction of the transient uncoupling factor is studied.
