摘要：为构造多翼吸引子超混沌系统提出了一种新方法.根据新超混沌系统状态变量z>0,给状态变量z乘以符号函数,得到一个四翼超混沌系统.基于构造的四翼超混沌系统,利用对正余弦型函数取整的方法,分别构造在x轴和z轴方向上产生4(2m-1)翼的超混沌系统.最终,设计出能够同时在x轴和z轴方向上产生多翼吸引子的超混沌系统.本文设计的超混沌系统的吸引子翼数仅与正余弦型函数的振幅大小有关.
A new method is proposed for constructing some hyperchaotic systems with multi-wing attractors.First,according to the state variable z>0 of the new hyperchaotic system,the state variablezis multiplied by symbolic function to obtain a four-wing hyperchaotic system.Then,based on the constructed four-wing hyperch a otic system,two hyperchaotic systems with 4(2m-1)wings are constructed on the axis x and the axis z directions respectively by using the method of round number for sine and cosine function.Finally,a hyperchaotic system is designed which can generate multi-wing attractor on the axis x and the axis z directions,simultaneously.The number of attractor’s wings of the proposed hyperchaotic system is only related to the amplitude of sine and cosine functions.
