Abstract :

Chaos is one of the most important phenomenons based on complex nonlinear dynamics . In this paper , we investgate chaos synchroniazation problems of a new 3D chaotic system.Based on the Lyapunov stability theory , a nonlinear control approach is presented for the synchronization between tow three-dimensional chaotic system . This system is a new three-dimensinal autonomous chaotiv system which is different from the other existing attractors and has larger Lyapunov exponent than the Lorenz system. In order to optimize this controller ,Genetic algorithm is applied. Genetic algorithm detects the best optimized values for gain of this controller. Fitness function is also considered as Total Square Error between master and slave system . Numerical simulations show the effectiveness of the presented controller.
