In the mathematics of
chaotic dynamical systems, in the Pyragas method of stabilizing a
periodic orbit, an appropriate continuous controlling signal is injected into the system, whose intensity is nearly zero as the system evolves close to the desired periodic orbit but increases when it drifts away from the desired orbit. Both the Pyragas and OGY (
