In this paper, we consider finite-time synchronization
between two complex dynamical networks
by using periodically intermittent control. Based on
finite-time stability theory, some novel and effective finitetime
synchronization criteria are derived by applying
stability analysis technique. The derivative of the Lyapunov
function V (t) is smaller than βV (t) (β is an arbitrary
positive constant) when no controllers are added
into networks. This means that networks can be selfsynchronized
without control inputs. As a result, the
application scope of synchronization greatly enlarged.
Finally, a numerical example is given to verify the effectiveness
and correctness of the synchronization criteria.
