“…Therefore, the generation of a multiscroll chaotic system and its circuit implementation are valuable subjects in research. Currently, many design methods are proposed to generate multiwing or multiscroll chaotic system, such as saw-tooth function [ 12 , 13 , 14 ], hyperbolic tangent function [ 15 , 16 ], hysteresis or saturated sequence [ 17 , 18 , 19 ], piecewise linear control method [ 20 , 21 , 22 ], and so on. Among the proposed schemes, it is common that the system equilibrium points are reconstructed by introducing nonlinear functions [ 23 , 24 , 25 , 26 ].…”
