：本文介绍了基于可变忆阻器的蔡氏电路中混沌动力学的实验分析。蔡氏电路中用作非线性电阻器的等效忆阻器包括运算放大器、乘法器、多个无源元件以及用于磁滞环控制的可变电阻器。使用忆阻器的控制电阻器作为可变电阻器来检查诸如吸引子和分叉之类的混沌动力学。此外，我们还展示了蔡氏电路中忆阻器磁滞回线的微妙依赖性。该电路是使用电子电路进行实验实现的，并记录了测量结果。所实现的电路在忆阻器的控制电阻中显示出从 4.3 k Ω 到 16.1 k Ω 的间歇性混沌动态。仿真和测量结果验证了所提出电路的混沌动力学可以使用可变忆阻器来创建和控制。
: This paper presents experimental analysis of chaotic dynamics in a variable memristor-based Chua ’ s Circuit. The equivalent memristor used as a nonlinear resistor of the Chua ’ s circuit comprises operational ampli fi ers, multipliers, several passive elements, and variable resistor for its hysteresis loop control. Chaotic dynamics such as attractors and bifurcation were examined using a control resistor of the memristor as a variable resistor. Moreover, we showed the subtle dependence on the hysteresis loop of the memristor in Chua ’ s circuit. The circuit was experimentally implemented using an electronic circuit and measurements were noted. The implemented circuit showed intermittent chaotic dynamics from 4.3 k Ω to 16.1 k Ω in control resistor of the memristor. The simulated and measured results veri fi ed that the chaotic dynamics of the proposed circuit could be created and controlled using a variable memristor.
