Experimental synchronization of non-identical chaotic circuits

In this paper, the experimental synchronization of chaotic circuits with different dynamical behavior is taken into account. Starting from both qualitative and quantitative considerations, a procedure, based on linear matrix inequalities, to assess the necessary condition for the synchronization of non-identical circuits is discussed. The results obtained are then evaluated through an experimental approach showing the synchronization of chaotic circuits differing either in parameter values or in their dynamical equations.
