Design and FPGA Realization of a Four-Wing Chaotic System

Abstract

A novel chaotic system is built based on making axis double polarities to enhance the complexity of attractors' topological structure. The attractors' structure of the system is varied from two-wing to four-wing. Theoretical analyses and numerical simulation are carried out to the novel chaotic system; it has one positive Lyapunov exponents by calculation. Other more, an electro circuit is designed and experimented by EDA technology based on FPGA.The result shows that the system has a four-wings attractor as numerical simulation also proves that theoretical analyses and numerical simulation are right.
