This paper proposes a fractional-order simplest chaotic system using a bi-stable locally-active memristor.The char-acteristics of the memristor and transient transition behaviors of the proposed system are analyzed,and this circuit is implemented digitally using ARM-based MCU.Firstly,the mathematical model of the memristor is designed,which is nonvolatile,locally-active and bi-stable.Secondly,the asymptotical stability of the fractional-order memristive chaotic system is investigated and some sufficient conditions of the stability are obtained.Thirdly,complex dynamics of the novel system are analyzed using phase diagram,Lyapunov exponential spectrum,bifurcation diagram,basin of attractor,and coexisting bifurcation,coexisting attractors are observed.All of these results indicate that this simple system contains the abundant dynamic characteristics.Moreover,transient transition behaviors of the system are analyzed,and it is found that the behaviors of transient chaotic and transient period transition alternately occur.Finally,the hardware implementation of the fractional-order bi-stable locally-active memristive chaotic system using ARM-based STM32F750 is carried out to verify the numerical simulation results.

人类的教育正处在一个大变革的前夜.这是摆在我们面前越来越清晰的事实.新世纪以来,尤其是最近几年,世界的剧变是史无前例的.rn第一,全球新冠肺炎疫情的持续蔓延.疫情实时大数据报告显示,截至12月13日,全球疫情死亡人数累计已经突破530万人,全球累计确诊超2.7亿例.疫情迫使许多学校停学,采取网络方式教学.近两年的教育实践也表明,对于大部分学生来说,在线学习是可以做到的.同时,对于在线学习的理念、技术和方法,教育界的研究也更为深入,取得了一些新成果.
A fractional-order difference equation model of a third-order discrete phase-locked loop (FODPLL) is discussed and the dynamical behavior of the model is demonstrated using bifurcation plots and a basin of attraction.We show a narrow region of loop gain w
Continuous-time memristor (CM) has been widely used to generate chaotic oscillations.However,discrete memristor(DM) has not been received adequate attention.Motivated by the cascade structure in electronic circuits,this paper intro-duces a method to casca
