Dual lag quasi-synchronization of a class of chaotic systems with parameter mismatch

Abstract

This paper studies the effect of parameter mismatch on the dual-lag synchronization of a class of coupled chaotic systems. Based on the Lyapunov stability theory, a new definition for global dual lag quasi-synchronization is introduced and used to analyze the synchronous behavior of coupled chaotic systems in the presence of parameter mismatch. Numerical simulations on the Ikeda oscillator are presented to verify the theoretical results
