The fourth basic circuit component, the memristor, has been proposed for a long time, but it is not mentioned in the experiment teaching system of Electrical and Electronic Technology. In this paper, an RC bridge oscillation chaotic circuit based on memristor is designed to solve this problem. The dynamical behavior of the circuit system is analyzed using Lyapunov exponents spectrum, bifurcation diagram, phase portrait and Poincaré map. A series of complex dynamical behaviors such as symmetric single-scroll coexistence, asymmetrical single-scroll coexistence, symmetric double-scroll coexistence and asymmetrical limit-cycle coexistence exist in the circuit system. This research plays a critical role in enriching students' knowledge and improving the experiment teaching system of Electrical and Electronic Technology.
第四种基本电路元件——忆阻器，虽已提出许久，但在《电气与电子技术》实验教学体系中却未被提及。本文设计了一种基于忆阻器的RC桥式振荡混沌电路来解决这一问题。利用李雅普诺夫指数谱、分岔图、相图和庞加莱映射对该电路系统的动力学行为进行了分析。该电路系统存在一系列复杂的动力学行为，如对称单涡卷共存、非对称单涡卷共存、对称双涡卷共存和非对称极限环共存。本研究对于丰富学生知识以及完善《电气与电子技术》实验教学体系具有关键作用。
