Dichotomy of nonlinear systems: Application to chaos control of nonlinear electronic circuit

In this Letter a new method of chaos control for Chua's circuit and the modified canonical Chua's electrical circuit is proposed by using the results of dichotomy in nonlinear systems. A linear feedback control based on linear matrix inequality (LMI) is given such that chaos oscillation or hyperchaos phenomenon of circuit systems injected control signal disappear. Numerical simulations are presented to illustrate the efficiency of the proposed method. (c) 2005 Elsevier B.V. All rights reserved.Physics, MultidisciplinarySCI(E)0ARTICLE3143-15235
