Intermittent dynamical control

This paper describes the method of synchronizing slave to the master trajectory using intermittent coupling. The information about master trajectory is limited only to the coordinates and timings of intersection points of that trajectory with the arbitrarily chosen Poincare section, making the coupling sporadic. The application of the method is first exemplified on the two identically coupled Rossler and Lorenz oscillators, and then is extended to the case when the two Rossler oscillators exhibit initially different dynamical properties (different values of the control parameters).
