Modeling and simulation of an electronic circuit for synchronizing multi-scroll chaotic oscillators

Abstract

This brief deals on the modeling and simulation of an analog electronic circuit based on operational amplifiers (Op Amps) for synchronizing two multi-scroll chaotic oscillators. An adaptive control approach was used to synchronize the chaotic waveforms generated in the master and slave systems in both domains: phase and time. Mathematical models of the master and slave chaotic systems were derived, including in the latter the adaptive control and taking into account, for both chaotic oscillators, the most influential performance parameters associated with Op Amps. Analytical results were validated by means of simulation results, confirming not only a good agreement between them, but also illustrate the benefits of the derived models.
