Abstract
We discuss the asymptotic frequency synchronization for the non-identical Kuramoto oscillators with time delayed interactions. We provide explicit lower bound on the coupling strength and upper bound on the time delay in terms of initial congurations ensuring exponential synchronization. This generalizes not only the frequency synchronization estimate by Choi et al. [Phys. D, 241(7):735{ 754, 2012] for the non-identical Kuramoto oscillators without time delays but also improves previous [Automatica, 48(12):3008{3017, 2012] in the case of homogeneous time delays is assumed to be less than =2. The proof relies on a Lyapunov functional approach.
