摘要: 基于共轭 Lorenz 系统,引入忆阻元件,提出了一个新型多翼磁控忆阻混沌系统, 此系统在改变参数时能够产生单翼、双翼、三翼、四翼等多种拓扑结构的混沌吸引子. 采用 相图、 Lyapunov 指数谱和分岔图分析了该系统的动力学特性,设计了该系统的模拟电路并 利用 Multisim 进行仿真. 电路仿真结果与数值分析结果吻合,从而验证了该系统的混沌行 为,亦表明了其可实现性. 最后,基于 Lyapunov 稳定理论设计了一个自适应滑模同步控制 器,在0. 25s 内实现了对给定信号的追踪, 0. 12s 内实现了对位置参数的快速辨识.

Abstract: A novel chaotic system with multi-wing attractors was proposed based on the conjugate Lorenztype system and by introducing flux-controlled memristor. Single-wing,two-wing,three-wing and four-wing chaotic attractors can be produced by changing the system parameters. The dynamic characteristics of the system were analyzed through phase diagrams,Lyapunov exponents,bifurcation diagram,etc. An analog circuit of the system was designed and simulated by Multisim. The circuit simulation results were consistent with the results of numerical analysis,which verifies the system's chaotic behaviors and shows its implementability. Finally,an adaptive sliding mode synchronous controller was designed based on the Lyapunov stability theory,and the given signal was tracked within 0. 25s and the position parameters was identified quickly within 0. 12s by the controller. 

Key words: flux-controlled memristor, chaotic system, sliding mode, adaptive synchronization control
