Synchronization of chaos in non-identical parametrically excited systems

In this paper, we investigate the Synchronization of chaotic systems consisting of non-identical parametrically excited oscillators. The active control technique is employed to design control functions based on Lyapunov stability theory and Routh-Hurwitz criteria so as to achieve global chaos synchronization between a parametrically excited gyroscope and each of the parametrically excited pendulum and Duffing oscillator. Numerical simulations are implemented to verify the results. (c) 2007 Elsevier Ltd. All rights reserved.
