Experimental study on control and synchronization of chaos in Chua's circuit

利用Multisim仿真软件研究了电路元件参数对称和不对称情况下蔡氏电路的混沌控制与同步。仿真结果综合表明:耦合电阻的大小及电路元件参数匹配对混沌信号控制与同步效果产生严重的影响。给出了混沌信号同步的耦合电阻参数范围,对进一步开展电路混沌创新性物理实验教学具有理论的指导意义。

This paper deals mainly with the experimental study on control and synchronization of chaos in Chua＇s circuit with the symmetry and dissymmetry circuit parameters by means of Multisim. The simulation results indicate that the size of coupling resistance and the parameter matching of circuit have a great effect on synchronization of chaos, and the parameter range of getting synchronization is given, which presents a theo-retical significance for the future work.
