Chaotic Synchronization and Information Transmission Experiments: A Fuzzy Relaxed H∞ Control Approach

Abstract: Abstract. This paper addresses the problem of the synchronization of a class of chaotic oscillators using techniques borrowed from a recently proposed control design based on Takagi-Sugeno (TS) fuzzy modeling. In order to attain better synchronization, this TS fuzzy modeling is combined with the robust H ∞ observer theory based on linear matrix inequalities. A laboratory setup based on Chua's oscillator circuit is used to demonstrate the main ideas of the paper. Information transmission experiments are perform… Show more

“…Although it appears to be stochastic, it occurs in a deterministic nonlinear system under deterministic conditions. In recent years, growing interests from physics, chemistry, biology, and engineering have stimulated the studies of chaos control [8,13], chaos synchronization [1,12,24], and chaos optimization [25]. Moreover, the synchronization of chaotic circuits for the secure communication has received much attention in the literature [15,20,22,26,27].…”

“…Synchronization is an important issue in many scientific areas, such as control theory [1,2], biological systems [3,4], telecommunication [5][6][7] and encryption [8,9], to name a few. Recently, its applications have been further extended to complex networks [10,11] and multi-agent systems [12,13], which are social sciences related.…”

“…Sistemas dinâmicos são chamados de caóticos se suaś orbitas são tipicamente não periódicas, limitadas dentro de uma região no espaço de estados e possuem alta sensibilidadeàs condições iniciais. A teoria caótica tem sido aplicada a vários campos de estudo como cardiologia (Cheng-Yu Yeh and Yau, 2012), circuitos eletrônicos (Guo and Liu, 2011), sincronização (Souza et al, 2008;Souza et al, 2012), comunicação segura (Cuomo and Oppenheim, 1993;Mozelli et al, 2007), conversão de energia (Hou, 2012), dinâmica dos fluidos (Lorenz, 1963) e economia (Goodwin, 1990).…”

Em (Ott et al, 1990), o método OGY foi desenvolvido permitindo converter um atrator caótico em um grande número de trajetórias periódicas instáveis injetando pequenas perturbações variáveis no tempo em um dos parâmetros acessíveis do sistema.…”
