摘要
为了研究双圆斑超级混沌吸引系统的非线性动力学行为,首先,提出了其数学微分方程,并进行了数值计算。然后,运用EWB电路仿真软件为系统设计了一个可行的实验电路,研究了系统的非线性动力学行为,给出了系统的周期运动和混沌吸引图像。最后,通过硬件电路实现了该混沌振荡电路。实验结果表明,双圆斑超级混沌吸引系统的动力学数学模型正确有效,数值计算与实验相一致。
In order to study the nonlinear dynamic behavior of a double-circular spot superchaotic attractor system,the mathematical differential equation was firstly proposed and its numerical calculation was carried out.Then a feasible experimental circuit was designed for the system by using EWB circuit simulation software.The nonlinear dynamic behavior of the system was studied,and the periodic motion and chaotic attraction images of the system were given.Finally,the chaotic oscillation circuit was realized by hardware circuit.The experimental results show that the dynamic mathematical model of the double circular spot super chaotic attraction system is correct and effective,and the numerical calculation is consistent with the experiment.
