From n-scroll to n×m-scroll attractors: A general structure based on Chua's circuit framework

In this paper, a general structure based on Chua's circuit framework is proposed for the generation of n×m scroll attractors. Starting from a modified Chua's circuit with n-scroll attractor, n × m-scrolls can be duly generated and observed by adding a simple staircase function onto the state equations. This method is successfully applied to different n-scroll Chua's circuits with equi-distance equilibrium points, and the results are verified by both simulations and experiments.
