Memristor Chaotic System With Symmetric Multistability and Their Synchronization Control
Considering the construction and synchronization control of high-dimensional chaotic systems,a syn-chronization control method for six dimensional memristor chaotic systems is proposed.Firstly,two memristors are introduced into a four-dimensional chaotic system to construct a six-dimensional memristor chaotic system and study the dynamic characteristics of the system.It was found that the memristor chaotic system generates various chaotic attractors and periodic limit cycles with changes in parameters and initial values.The system exhibits sym-metric bifurcation behavior and symmetric multistability phenomena.Secondly,an error system and synchroniza-tion controller are designed to verify synchronization control effects with Matlab.The results show that the pro-posed method achieves system synchronization in a short time,and the synchronization effect is good.Finally,FP-GA is used to implement the digital circuit of the system.The images observed through the oscilloscope are con-sistent with the simulation results,which proves the feasibility of the design.
