“…The trajectory switches irregularly from one to the other symmetric locations but always repelled by the third saddle focus origin. Multiscroll attractors have a larger number of scrolls (n>2, n is the number of scroll) and mostly been implemented [Kapitaniak et al, 1990;Kapitaniak et al, 1994;Suykens et al, 1993;Arena et al, 1996;Tang et al, 2001;Yalcin et al, 2000;Yalcin et al, 2001;Lü et al, 2003;Ozoguz et al, 2002;Cafagna et al, 2003;Lü et al, 2004;Lü et al, 2004a;Yu et al, 2006; by introducing additional saddle foci in terms of added breakpoints in the model system. Multiscroll has been reported in unidirectionally or diffusively coupled self-oscillating Chua circuits [Kapitaniak and Chua, 1994] and in arrays of 1-D cellular neural networks (CNN) [Suykens and Vandewalle, 1993], where the birth of a double-double scroll attractor is found in intermittent bursts from 3D manifold to higher dimensions for weaker coupling.…”
