Projective-lag synchronization of coupled multidelay feedback systems

摘要

In this study, we investigate the projective-lag synchronization model of coupled multidelay feedback systems. The master synchronizes with the slave under the lag synchronization scheme and there is a scale factor between the amplitudes of state variables. The driving signal is constituted by the sum of multiple nonlinear transformations of a delayed state variable. A sufficient condition for synchronization is considered under the Krasovskii-Lyapunov theory. The effectiveness of the proposed model is demonstrated and verified by examining specific examples using modified Mackey-Glass and Ikeda systems.
