A New Six-dimensional Hyperchaotic System and Its Circuit Implementation

By mixing the Duffing chaotic system with the lorenz chaotic system,a new multi-parameter six-dimensional hyperchaotic system with a more complex structure is produced.The Lyapunov exponent simulation results of seven parameters in the system show that the hyperchaotic system has strong chaotic features.The features of phase space maps,Lyapunov exponents maps,Poincare maps,power spectrm and time domain of the new hyperchaotic system are analysed.The circuit implementation and simulation experiments of the new chaotic system are designed.The results of theoretical analysis and experimental show that the system belongs to a new hyperchaotic system.
