<![CDATA[The chaotic system plays an important role in information communication, electrical equipment, computer cryptography and so on. In this paper, four new high-dimensional complex hyperchaotic systems are found. A new overlaying regularity to generate a new high-dimensional complex hyperchaotic system is found by overlaying a series of low-dimensional chaotic system with the Duffing chaotic system. The regularity to generate high-dimensional complex hyperchaotic system is analyzed. The features of chase space maps and Lyapunov exponents’ maps are analyzed. The results of theoretical analysis and experiment show that new systems having strong chaotic features. DOI: http://dx.doi.org/10.11591/telkomnika.v11i8.3084]]>
