Experimental Investigation Of Adaptive Synchronization Of Two Rossler Circuits

Mattia Frasca, Luigi Fortuna, Arturo Buscarino, Lucia Valentina Gambuzza, Sergio Chessari
In this work we investigate synchronization in an experimental setup consisting of two diffusively coupled electronic chaotic circuits where the coupling gain is controlled by an adaptive law. We show that an adaptive law, which assumes that the gain changes are proportional to the error between the states of the two circuits, suffers from the presence of unavoidable tolerances in the circuit parameters. For this reason, we introduce a new adaptive law which on the contrary is able to handle the problem in the presence of circuital mismatches.
