Abstract :

Synchronization of a Class of Neutral Chaotic Systems based on Adaptive Sliding Mode Control Approach Synchronization of a Class of Neutral Chaotic Systems based on Adaptive Sliding Mode Control Approach Synchronization of a Class of Neutral Chaotic Systems based on Adaptive Sliding Mode Control Approach In this paper, adaptive control mechanism for finite time synchronization of a specific class of neutral chaotic systems is considered equal to unknown Delays disturbance and uncertainty. Delays and parameters are considered and different for two neutral chaotic systems equal to the master and the slave. The neutral chaotic system is introduced using a positive Lyapunov exponent and finite Attractor. in the proposed adaptive control mechanism two linear and adaptive sliding mode controllers have been used for synchronization.in the proposed approach control mechanism,the rules for updating the unknown parameters have been introduced by Lipshitz condition in chaotic system and use of Lyapunov function stability proposed control system in robust synchronization mentioned system have been confirmed. Finally, synchronization is performed between the master and slave neutral chaotic system )Jark and Gensiotsio( with nonlinear uncertainty and external disturbance as well as parameters and unknown time delay. Examination of the simulation results shows that the controller overcame the external disturbance and boundary uncertainty in the shortest time. And The estimation of the parameters of the main system is well done, which indicates the accuracy of the theory analysis.
