Projective Lag Synchronization of Delayed Chaotic Systems via Intermittent Control with Two Sub-periods

Intermittent control strategy is used for achieving projective lag synchronization between two delayed chaotic systems. Different from the commonly used single-periodic control, the control period adopted in this paper is two-periodic, where a complete control period consists of two sub-periods. Some synchronization criteria in the form of algebraic inequalities are derived by way of Lyapunov stability theory. Finally, a time-delay Chua's circuit system is taken as the simulation example, and the numerical results demonstrate the effectiveness of the proposed method.
