在这封信中，蔡氏电路与有源可变忆阻器是第一次。可变忆阻器背后的中心概念是其忆导可以通过改变描述忆阻器的通量和电荷之间的关系的三次函数来控制。研究发现，基于可变忆阻器的蔡氏电路的混沌动力学可以很容易地根据忆阻器的忆导轮廓进行控制。通过数值分析，深入研究了电路中的可控混沌动力学。从时间序列、频谱、相态、分岔和李雅普诺夫指数等方面验证了采用可变忆阻器的蔡氏电路的丰富动力学特性。这些结果也得到了实验室实验的证实。
In this letter, the Chua’s circuit with an active variable memristor is presented for the first time. The central concept behind the variable memristor is that its memductance could be controlled by changing the cubic function which describes a relationship between the flux and charge of the memristor. It was found that chaotic dynamics of the variable-memristorbased Chua’s circuit could be easily controlled according to the memductance profile of the memristor. The controllable chaotic dynamics in the circuit were studied thoroughly by the numerical analysis. The rich dynamics of the Chua’s circuit using the proposed variable memristor were verified in terms of the time series, frequency spectra, phase states, bifurcation and Lyapunov exponents. These results were also confirmed by laboratory experiments.
