A new four-dimensional chaotic system is reported in this paper. Basic dynamic properties of the new system are investigated via theoretical analysisnumerical simulationLyapunov exponentLyapunov dimension and Poincare diagrams. Finally the chaotic circuit is designed and realized by the Multisim software. It confirms that the chaotic system is different from the exisiting chaotic systems and is a new hyperchaotic system.
