Dynamics of Hyperchaotic Coupled Chua Circuits: Generation of new NxM-Scroll Attractors

In this paper the attention is focused on the generation of new hyperchaotic attractors from coupled Chua circuits. By exploiting sine functions as nonlinearities, the proposed technique enables nxm-scroll attractors to be obtained. In particular, it is shown that nxm-scroll dynamics can be easily designed by modifying four parameters, which characterize the circuit nonlinearities. Finally, some examples are reported to illustrate the capability of the proposed design technique.
