Novel Grid Multiwing Butterfly Chaotic Attractors and Their Circuit Design

A new method is presented generating grid multiwing butterfly chaotic attractors in this brief. By designing piecewise hysteresis functions to take the place of the state variables of the Lorenz system directly, a novel grid multiwing butterfly chaotic system is constructed. The Lyapunov exponent and the bifurcation diagram are studied. Furthermore, an electronic circuit is designed to implement the system. The experimental results are in agreement with numerical simulation results, which verify the availability and feasibility of this method.
