Synchronization of uncertain chaotic systems using dynamical compensator

At present, the uncertain system controller parameters are almost designed according to the upper bound of norm of the uncertainties, which often result in the designed controller has a serious conservative. In order to overcome this shortcoming, this paper proposed a new synchronization strategy for uncertain chaotic systems by using dynamic compensator technique, which is robust to uncertainties. finally a typical numerical example is given to demonstrate the effectiveness of the result obtained.
