The fast synchronization problem for a class of complex dynamical networks
with time varying delay by means of periodically intermittent control is studied.
Based on the finite-time stability theory and periodically intermittent
control technique, some sufficient synchronization criteria are obtained to
guarantee the fast synchronization. Furthermore, the essential condition for
guaranteeing periodically intermittent control realized in finite time is given
in this paper. Finally, two examples are illustrated to verify the proposed
