| 1 | Hidden Attractors in a Delayed Memristive Differential System with Fractional Order and Chaos Synchronization显示文摘As an important research branch,memristor has attracted a range of scholars to study the property of memristive chaotic systems.Additionally,time⁃delayed systems are considered a significant and newly⁃developing field in modern research.By combining memristor and time⁃delay,a delayed memristive differential system with fractional order is proposed in this paper,which can generate hidden attractors.First,we discussed the dynamics of the proposed system where the parameter was set as the bifurcation parameter,and showed that with the increase of the parameter,the system generated rich chaotic phenomena such as bifurcation,chaos,and hypherchaos.Then we derived adequate and appropriate stability criteria to guarantee the system to achieve synchronization.Lastly,examples were provided to analyze and confirm the influence of parameter a,fractional order q,and time delayτon chaos synchronization.The simulation results confirm that the chaotic synchronization is affected by a,q andτ. | Dawei Ding Yecui Weng Nian Wang | 2020 | Journal of Harbin Institute of Technology(New Series)2020，27，1： | 1 |
| 2 | Dynamics Analysis of Fractional Order Memristive Time Delay Chaotic System and Circuit Implementation显示文摘The integer order memristive time delay chaotic system has attracted much attention and has been well discussed.However,the fractional order system is closer to the real system.In this paper,a nonlinear time delay chaotic circuit based on fractional order memristive system was proposed.Some dynamical properties,including equilibrium points,stability,bifurcation,and Lyapunov exponent of the oscillator,were investigated in detail by theoretical analyses and simulations.Moreover,the nonlinear phenomena of coexisting bifurcation and attractor was found.The phenomenon shows that the state of this oscilator was highly sensitive to its initial value,which is called coexistent oscillation in this paper.Finally,the results of the system circuit simulation accomplished by Multisim were perfectly consistent with theoretical analyses and numerical simulation. | Dawei Ding Hui Liu Yecui Weng Xiaolei Yao Nian Wang | 2020 | Journal of Harbin Institute of Technology(New Series)2020，27，2： | 1 |
