Applying the method synchronization from PC on the electronic circuit chaotic from type attraction – repulsion.

Abstract

We discuss in this studying, one of the type of synchronization technique, that called Pecora & Carroll (PC), and applying this method on one of type Chua circuit, which have nonlinear part from type attraction – repulsion. The case synchronization is succeeded in the circuit, when we sent the variable   X1, in addition to, the parameter of coupling system is match, but, when the parameter became mismatched we notice case non synchronization or called quasi- synchronization.  The synchronization is Completely hidden when we tried sent the variable    X2, in both cases matched & mismatched parameter. The adaptive control method was tested on the chaotic circuit, this method succeed after time t=5sec.
