摘　　要：将两个磁控忆阻器引入到经典Shinriki振荡器中,构建了一个含双忆阻的混沌振荡电路.采用增量磁通-电荷分析方法,对所构的双磁控忆阻Shinriki电路进行降维处理,得到了双忆阻振荡器的三阶降维模型.在韦库域内,研究系统的共存分岔行为、反单调现象,并重构振荡器的极端多稳态现象,分析多稳态域内的簇发放电行为.此外,基于Multisim电路仿真软件搭建了降维后系统的等效电路,并捕捉到相应的吸引子相轨迹图,验证了动力学分析的正确性.In this paper,by adding two flux-controlled memristors into the classic Shinriki oscillator,a chaotic oscillation circuit is constructed.With the incremental magnetic flux-charge analysis method,the Shinriki circuit based on the two flux-controlled memristors conducts dimensionality reduction,meanwhile the third-order dimensionality reduction model is obtained.Then,the coexisting birfurcation and antimonotonic phenomenon in the flux-charge domain are discussed.At the same time,the extreme multistablity of the oscillator is reconstructed and the bursting behavior in the multistable domain is analyzed.In addition,the equivalent circuit of the system after dimensionality reduction is built and the corresponding phase trajectory diagram is captured,which verifies the correctness of the dynamic analysis.
