On the robust chaos synchronization of RCLSJ models

This paper is concerned with the robust chaos synchronization problem for coupled RCL-shunted Josephson junction (RCLSJ) models. The variable structure control (VSC) technique is introduced to propose a nonlinear controller such that the coupled RCLSJ models with different parameters can be synchronized even when the uncertainties are present. An example is included to illustrate the results developed in this paper.
