Estimation on error bound of lag synchronization of chaotic systems with time delay and parameter mismatch

摘要

This paper studies the effect of parameter mismatch on lag synchronization of chaotic systems with time delay in the framework of master-slave configuration. It shall be shown that lag synchronization of coupled systems may achieve weakly in the presence of small parameter mismatches. The error bound of lag-synchronization arising from the parameter mismatches is also estimated by rigorously theoretical analysis. Numerical simulations on a Lu oscillator are presented to verify the theoretical results.
