Abstract

In this paper an observer based synchronization for a 4-D Modified Lorenz-Stenflo (MLS) chaotic system is reported. The proposed work uses a scalar coupling signal for synchronization of the 4-D MLS chaotic system in contrary with the conventional diagonal coupling signal. Based on Liapunov´s stability theory, an inequality is derived for the synchronization of proposed system. Simulation is used to demonstrate the effectiveness of the proposed scheme under the Nearest-neighborhood coupling and the Global coupling configurations. Simulation results suggest that proposed scheme is working satisfactorily.
