Hyperchaotic coupled chua circuits:: An approach for generating new n x m-scroll attractors

In this paper an approach for generating new hyperchaotic attractors from coupled Chua circuits is proposed. The technique, which exploits sine functions as nonlinearities, enables n x m-scroll attractors to be generated. In particular, it is shown that n x m-scroll dynamics can be easily designed by modifying four parameters related to the circuit nonlinearities. Simulation results are reported to illustrate the capability of the proposed approach.
