Abstract :
A new method of virtual unknown parameter is proposed to synchronize two different systems with unknown parameters and disturbance in finite time. The information signal hidden in chaotic signal is transmitted and can be successfully recovered at the receiver once synchronization is achieved. Numerical simulations show that the present method is effective.
