摘要
提出了一种用处处光滑的反正切函数序列生成多维多涡卷网格混沌吸引子的方法,可以生成一维n涡卷、二维n×m网格多涡卷和三维n×m×l网格多涡卷混沌吸引子。平衡点分析、数值仿真、Lyapunov指数谱、分岔图和Poincaré映像都表明系统是混沌的。用简单的线性反馈控制实现了同结构网格多涡卷混沌系统之间的同步,可应用于保密通信。简单的理论分析和数值仿真证明了该方法的有效性。
A smooth arc tangent function series approach for creating multi-directional multi-scroll grid chaotic attractors was proposed,including one-directional n-scroll,two-directional n×m-grid scroll,and three-directional n×m×l-grid scroll chaotic attractors.The chotic properties were studied by equilibrium points analysis,numerical simulation,Lyapunov exponents spectrum,bifurcation diagrams and Poincaré section diagrams.Synchronize the two grid multi-scroll chaotic systems with same structure by designing simple linear feedback control lows,which is applied to secure communication.The effectiveness of this method has been verified by simple analysis and numerical simulation.
