Eight dimension seven-order hyperchaotic system and its circuit implementation

In order to generate more complex chaotic attractors, an eight-dimensional seven-order hyperchaotic system is constructed, and relevant chaotic attractors can be obtained by Matlab numerical simulation. Lyapunov exponents validate that the system is hyperchaotic. Implementation circuit of this system is designed, and circuit simulation can be done by using Multisim. Circuit simulation result is identical to system simulation completely. Hyperhaotic behavior of the system is proved farther. A new chaotic signal source is provided for practical application based on chaos such as secrecy communication and signal encryption fields.
