Selection of multi-scroll attractors in Jerk circuits and their verification using Pspice

摘要

In this paper, a feasible feedback scheme is used to stabilize the multi-scroll attractors in the Jerk circuit, and the controller is realized using mixed Heaviside function. It is found that arbitrary number (n = 2, 3, 4, 5,...) of multi-scroll attractors can be selected from a controlled Jerk circuit, and thesemultiscroll attractors can be reproduced using Pspice. The implementation of circuit and controller using Pspice is also presented. The potential mechanism could be that an external forcing in the Sine type is practical to generate a group of equilibrium points, and a linear controller composed of Heaviside function is effective to stabilize the n-scroll attractors in the chaotic systems.
