A simple adaptive controller for chaos and hyperchaos synchronization

A novel and simple adaptive feedback controller is proposed for chaos and hyperchaos synchronization. In comparison with previous methods, the present control scheme is not only simple but employs only one control strength, converges very fast and also suitable for a large class of chaotic and hyperchaotic systems. In addition, the synchronization is efficient in the presence of noise. Numerical simulations are used to validate and demonstrate the effectiveness of the method.
