Uncertain Chua system chaos synchronization using single variable feedback based on adaptive technique

摘要

This paper treats the chaos synchronization problem of uncertain chaotic Chua circuit system. Based on adaptive technique, the proposed controller is featured with (a) the only single variable information from the master system is needed; (b) the synchronization can also be achieved while some parameters of the master system are perturbed; (c) the bound of the uncertainty is estimated by an adaptive control law. Finally, the effectiveness of the proposed control law is also illustrated by the numerical simulation on Matlab environment.
