Annotation	During previous decades, chaotic systems have been subjected to intensive research, in particular, using the methods of the automatic control theory. One of the prominent problems here is the so-called synchronization of two or more chaotic systems. Even in case, when having two identical copies of the same chaotic system with practically the same initial conditions, thanks to strong dependence on initial data, after some time their behavior may be very different. In such a way, chaotic oscillations tend to be de-synchronized, unless some synchronizing influence is being imposed. Synchronization is usually achieved by transferring certain synchronizing signal from one chaotic system into the other one. This signal shlould have the least possible dimension, preferable it should be a scalar time function. As a suitable theoretical framework for synchronization appears to be the notion of the observer introduced by automatic control theory.
