Emerging multi-double-scroll attractor from variable-boostable chaotic system excited by multi-level pulse
This study reports a simple approach to emerging multi-double-scroll attractor from a variable-boostable chaotic system via multi-level pulse excitation, which is achieved by replacing a constant controller with a multi-level pulse function. To intuitively show the simple and feasible approach, a four-double-scroll chaotic attractor coined in such a system with four-level pulse excitation is taken as a paradigm.
