| Abstract: | A new hyperchaotic system based on Volta's system is presented via adding linear control.The hyperchaotic behavior and chaotic behavior of this new 4D Volta's system are studied by Bifurcation diagram, Lyapunov exponents spectrum and phase diagram.The hyperchaotic behavior and chaotic behavior of this new 4D Volta's system with varying parameters are studied by Bifurcation diagram, Lyapunov exponents spectrum and phase diagram.Then, the Lyapunov stability theorem and the adaptive control theory are both employed to realize synchronization of the two hyperchaos with unknown parameters.Our simulation results have demonstrated effectiveness and validity of the proposed method. |
| Keywords: | hyperchaotic system feedback control Lyapunov exponents spectrum |
