The external disturbances are inevitable in the synchronization process.In this paper,the H∞ synchronization problem for a class of nonlinear system is investigated via intermittent control based on the H∞control theory.Different from the previous results,the control and rest window width are variable in this paper,that is aperiodically intermittent control.Owing to the switching characteristics of intermittent control,a switching-time-various Lyapunov function combined with the convex combination technique...
