【 摘 要 】

References(9)Cited-By(1)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 amplifiers, 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 kΩ to 16.1 kΩ in control resistor of the memristor. The simulated and measured results verified that the chaotic dynamics of the proposed circuit could be created and controlled using a variable memristor.
