Generating multi-double-scroll attractors via pulse control technique

In this paper, a novel approach for generating multi-double-scroll attractors(MDSA) without changing the original nonlinear functions is presented. By using the multi-level-logic pulse excitation technique in double scroll chaotic systems, MDSA can be generated. Furthermore, the corresponding realization circuits are designed. The Pspice results are in agreement with numerical simulation results, which verify the availability and feasibility of this method.
