摘要: 基于三阶经典Chua电路,设计了一个含有两个异构磁控忆阻器的非线性电路,建立了其无量纲五阶数学模型。由于两个磁控忆阻器的特性方程在设计中的相异性,它们所在的位置是关于电容形成对称结构。对系统的平衡点的稳定性和李雅普诺夫指数进行分析,证明该异构磁控忆阻电路混沌特性的存在。采用Multisim电路仿真软件分别对五阶异构忆阻Chua系统模型和两个异构磁控忆阻器进行电路实现,数值计算和电路实验结果表明异构磁控忆阻Chua电路具有丰富的混沌行为,且可勾画出完全相同的混沌吸引子和类紧磁滞回归轨迹。

Abstract: A nonlinear circuit containing two heterogeneous magnetron memristors which based on the three-order classic Chua circuit is designed, its dimensionless fifth-order mathematical model is proposed. Due to the difference in the design of the characteristic equation of the two magnetron memristors, their positions form a symmetrical structure with respect to the capacitor. The existence of chaotic properties is proved by analyzing the stability of the system equilibrium point and Lyapunov exponents. The model of five-order heterogeneous memristive Chua system and two heterogeneous magnetron memristors are implemented by Multisim. Numerical calculation and experimental results show that heterogeneous magnetron memristive Chua circuit has a wealth of chaotic behavior and can outline the same chaotic attractors and hysteresis regression curves.

Key words: Chua circuit, magnetron memristors, circuit simulation, hysteresis regression curve, chaos attractors
