Abstract

This paper proposes a new method of chaos synchronization for chaotic system under parameter mismatch. Based on Lyapunov stability theory, the proposed synchronization method is robust to parameter mismatch. The slave system can synchronize to the master system even the parameter error is large. This can overcome the parameter mismatch problem when using the circuit components to realize the synchronization. Finally, numerical simulations are given to demonstrate the effectiveness of the proposed method..
