Simulation and Experimental Realization of Multi-Scroll Chaotic Oscillators

Abstract

This article shows the simulation and experimental realization of a multi-scroll chaotic oscillator based on saturated nonlinear function (SNLF) series. First, the simulation is performed by MATLAB using the mathematical description of the oscillator. At this step, it is shown how to increase the number of scrolls by augmenting the SNLF. Second, the mathematical description is implemented with electronic devices and simulated by using the behavioral model of commercially available operational amplifiers. The circuit simulation of the multi-scroll chaotic oscillator is performed showing how to generate even and odd number of scrolls. Finally, the simulated circuit is realized experimentally and the results confirm good agreement with theoretical simulations.
