基于HP-二氧化钛记忆阻器的实际模型和蔡氏电路,设计了一种新的混沌振荡器。从理论上和数值上研究了振子的一些基本动力学行为,包括平衡点、Lyapunov指数谱和关于不同电路参数的分叉。通过仿真和实验对该振荡器产生的混沌吸引子进行了描述,得到了较好的一致性。分析的主要结果是,所提出的振子不存在暂态混沌,出现了弱超混沌。此外,它的稳定性对初值不敏感,从而产生连续稳定的混沌振荡信号,用于混沌应用。
We design a new chaotic oscillator based on the realistic model of the HP TiO2 memristor and Chua's circuit. Some basic dynamical behaviors of the oscillator, including equilibrium set, Lyapunov exponent spectrum and bifurcations with respect to various circuit parameters, are investigated theoretically and numerically. Chaotic attractors generated by the proposed oscillator are described with simulations and experiments, showing a good agreement. The main finding by analysis is that the proposed oscillator has no transient chaos and weak hyper-chaos appears. Furthermore, its stability is insensitive to its initial values, thereby generating continuous and stable chaotic oscillation signals for chaos-based applications.
