Abstract

Abstract:

A model of the modified Chua's chaotic system was constructed to produce multi-scroll chaotic attractors,replacing the typical Chua's diode with the sign function in the typical Chua's circuit. The method is to make equilibrium point located in the center of two adjacent breakpoints,and keep scrolls and bond orbits alternated with each other. Both model analysis and Matlab simulation show that the system generates 10 scrolls chaotic attractors. Finally,the design of the hardware circuit produces at a maximum of 10 scrolls hardware experimental results. Hardware experiments,analysis and simulation are almost accordance, which further proved the existence of the system.

Key words: chaos, modified Chua's circuit, multi-scroll, chaotic attractors, hardware implementation
