Chua system chaos synchronization using single variable feedback based on LaSalle invariance principal

This paper treats the chaos synchronization problem of chaotic Chua circuit system. Based on LaSalle invariance principal, the proposed controller is featured that (a) only single variable information of the master system is needed; (b) the control law is a simple linear controller with low gain. Finally, the effectiveness of the proposed control law is also illustrated by the numerical simulation on Matlab environment.
