The new open-plus-close-loop (OPCL) method of control complex dynamic systems developed by Jackson and Grosu [Physica D 85, 1 (1995)] is used for synchronization of two identical oscillators. The synchronization is efficient for a very large level of noise. Numerical examples are given for two Lorenz systems and two logistic maps. The coupling is analytically justified.
