It is easy to construct a hyperchaotic system,and many systematic approaches,based on Chua system,can be used for generating multi-scroll attractors. However, few reports discuss the smooth Lorenz-like system with multi-wing attractors,and the attractors with both hyperchaotic dynamics and multi-wing topological structure are seldom reported. Based on the existing smooth hyperchaotic system,the common characteristics of these systems are analyzed. A novel coordination transformation method is used for converting all the attractors' topological structure from two-wing to four-wing. Moreover,the hyperchaotic property is preserved in resulting system,the complexity of attractors is enhanced,and they are more suitable to be used in secure encryption communication.
