Design and FPGA circuit implementation of a four-wings hyperchaotic system

摘要

The third equation of hyperchaotic system are modified and polarities are made double for z axis to enhance the complexity of attractors' topological structure. The attractors' structure of the system varies from two-wings to four-wings. Theoretical analyses and numerical simulation are carried out to the novel hyperchaotic system; it has two positive Lyapunov exponents by calculation. Other more, a electro circuit is designed with modular method and experimented. The result shows that the system has a four-wings attractor as numerical simulation also proves that theoretical analyses and numerical simulation are right.
