RESYNCHRONISATION OF GLOBALLY COUPLED CHAOTIC OSCILLATORS USING ADAPTIVE-CONTROL

Using a parametric adaptive control we synchronized or resynchronized perturbed oscillators in an array of globally coupled chaotic oscillat ors possibly in the presence of large noise. The method, based on the Kalman filter, was applied to a Henon map lattice. This method can be viewed as an adaptive mechanism. In biological systems, adaptive mecha nisms may confer to complex self-regulated systems an increased resist ance to signal degradations due to large environmental perturbations.
