| Abstract: | A novel chaotic system is built based on making z axis double polarities to enhance the complexity of attractors' topological structure.The attractors' structure of the system is varied from two-wings to four-wings.Theoretical analysis and numerical simulation are carried out for the novel chaotic system;the calculation indicates that the system has one positive Lyapunov exponent.And the system is operated by using a digital electro circuit design.It proves that theoretical analysis and numerical simulation... |
