Master-slave synchronization of 4th order Lü chaotic oscillators via linear output feedback
Résumé
We solve the problem of master-slave synchroniza- tion of fourth-order Lü's hyperchaotic systems via feedback con- trol. We use only one control input that enters in the slave system. We show that this simple feedback suffices to synchronize both systems exponentially fast. We provide a proof of stability and con- vergence (hence, that synchronization takes place) via Lyapunov's second stability method. We provide some numeric simulations that illustrate our findings.
