| Abstract: | In this paper,a hyperchaotic system is proposed.The system is constructed by introducing an additional state variable into the third-order Lorenz system.Some basic properties are analyzed in detail,and the Lyapunov spectrum of this system is gained through computation,so the existence of hyperchao is verified.Moreover,an analysis electronic circuit is designed,and various hyperchaotic attractors of this system are observed from the circuit experiments. |

| Keywords: | hyperchaotic attractor Lyapunov spectrum circuit implementation |
