Robust synchronization of chaotic behavior in unidirectional coupled RCLSJ models subject to uncertainties

This paper deals with the problem of robust synchronization for a class of unidirectional coupled RCL-shunted Josephson junction (RCLSJ) models. A nonlinear controller is proposed based on variable structure control technique to ensure that these coupled RCLSJ models with different parameters can be asymptotically synchronized even when uncertainties are present in the coupled system. Finally, a comparative example is given to emphasize the simplicity and robustness of the proposed method.
