چکیده
This paper presents an adaptive algorithm to synchronize unified chaotic systems in the presence of unknown system parameter and bounded disturbances. Based on Lyapunov-like analysis, an adaptive scheme is proposed to make the synchronization error asymptotically null. Simulation results are provided to demonstrate the effectiveness and feasibility of the proposed synchronization method. Keywords Synchronization, Lyapunov methods, chaotic systems. Resumo Neste artigo apresenta-se um algoritmo adaptativo para sincronizar sistemas caóticos unificados na presença de parâmetro desconhecido e distúrbios limitados. Com base em uma análise tipo Lyapunov-like um esquema adaptativo é proposto e provado que o erro de sincronização converge assintoticamente para zero. Um exemplo de aplicação é apresentado para mostrar o desempenho do método de sincronização proposto. Palavras-chave Sincronização, métodos de Lyapunov, sistemas caóticos.

Fractional order robust adaptive intelligent controller design for fractional-order chaotic systems with unknown input delay, uncertainty and external disturbances
In this paper, a fractional-order robust adaptive intelligent controller (FRAIC) is designed for a class of chaotic fractional order systems with uncertainty, external disturbances and unknown time-varying input time delay. The time delay is considered both constant and time varying. Due to changes in the equilibrium point, adaptive control is used to update the system's momentary information a...
متن کاملAnti-synchronization and synchronization of T-system
In this paper, we discuss the synchronization and anti-synchronization of two identical chaotic T-systems. The adaptive and nonlinear control schemes are used for the synchronization and anti-synchronization. The stability of these schemes is derived by Lyapunov Stability Theorem. Firstly, the synchronization and anti-synchronization are applied to systems with known parameters, then to systems...

Heart chaotic system and the ability of particle swarm optimization (PSO) method motivated us to benefit the method of chaotic particle swarm optimization (CPSO) to synchronize the heart three-oscillator model. It can be a suitable algorithm for strengthening the controller in presence of unknown parameters. In this paper we apply adaptive control (AC) on heart delay model, also examine the sys...

In this paper, an optimal adaptive sliding mode controller is proposed for anti-synchronization of two identical hyperchaotic systems. We use hyperchaotic complex T-system for master and slave systems with unknown parameters in the slave system. To construct the optimal adaptive sliding mode controller, first a simple sliding surface is designed. Then, the optimal adaptive sliding mode controll...
متن کاملRobust Adaptive Synchronization of Unified Chaotic Systems
This paper proposes an adaptive methodology to estimate the unknown master system parameter and synchronize unified chaotic systems, even if bounded system disturbances are present. Based on both Lyapunov theory and Barbalat’s Lemma, a robust adaptive scheme is proposed to make the synchronization error asymptotically null. Simulation results are provided to demonstrate the effectiveness and fe...
