Control Theory Appl. 28, No. 3, 389-394 (2011). 2011 South China University of Technology, Guangzhou ZH variable parameter Chua's circuit synchronization Summary: A new synchronization method is proposed for the non-autonomous Chua's circuits with small disturbances in voltage amplitude and phase. In this method, the non-autonomous equation is transformed into the autonomous equation with initial values representing the small perturbed voltage amplitude and phase in the original non-autonomous equation. Thus, the chaotic synchronization with mismatch parameters can be realized by the chaotic synchronization with deterministic parameters. Using one-way coupled synchronization method and the nonlinear differential geometric control theory about stability theory of cascade-connected system to reduce the dimension, we obtain the conditions for coupling coefficients in the synchronization of two systems, thus we solve the problem of synchronization of two systems with mismatch parameters. The simulation results show that this method can realize fast chaotic synchronization between two systems with mismatch parameters.
