Based on the work in Int. J. of Bifurcation and Chaos vol.12(2002)1423,we address the circuitry realization problem of Chen chaotic system.We derive available circuit parameters with which we simulate the circuit on the simulation softwareElectronic Workbench.After realizing the Chen system in the circuit,we observe the chaotic figure on the oscillograph.Employing the synchroniation method using single variable coupling feedback,we conduct the synchronization experiments and obtain the parameter range for controlling the synchronization between two Chen's systems.
