Anti-synchronization and intermittent anti-synchronization of two identical hyperchaotic Chua systems via impulsive control

This work is concerned with anti-synchronization and intermittent anti-synchronization of two identical hyperchaotic Chua systems using an impulsive control technique. Sufficient condition of anti-synchronization is derived from Lyapunov stability theory, and numerical simulation results are presented to demonstrate the effectiveness of the proposed anti-synchronization scheme. In addition, we report an interesting phenomenon: when the second state of the response system is controlled via impulse, there exist narrow regions of the impulsive control gain, where intermittent anti-synchronization can occur.
