Global Synchronization of Four-wing Chaotic Systems by Sliding Mode Control
نویسنده
چکیده
This paper investigates the global chaos synchronization of identical Qi four-wing chaotic systems (Qi et al., 2008), identical Liu four-wing chaotic systems (Liu, 2009) and identical Wang chaotic systems (Wang et al., 2009). The stability results derived in this paper for the complete synchronization of the three pairs of identical four-wing chaotic systems are established using Lyapunov stability theory. Since the Lyapunov exponents are not required for these calculations, the sliding mode control method is very effective and convenient to achieve global chaos synchronization of the four-wing chaotic systems. Numerical simulations are shown to illustrate and validate the synchronization schemes derived in this paper for the identical four-wing chaotic systems.

Global Finite Time Synchronization of Two Nonlinear Chaotic Gyros Using High Order Sliding Mode Control
In this paper, under the existence of system uncertainties, external disturbances, and input nonlinearity, global finite time synchronization between two identical attractors which belong to a class of second-order chaotic nonlinear gyros are achieved by considering a method of continuous smooth second-order sliding mode control (HOAMSC). It is proved that the proposed controller is robust to m...
