Abstract: We describe the implementation of the Ott-Grebogi-Yorke method of controlling chaos in a physical system. This method requires only small time dependent perturbations of one system parameter and does not demand the use of model equations to describe the dynamics of the system. One advantage of the OGY method is that, between these perturbations, the system remains on chaotic trajectories. One can thus use the sensitivity of the chaotic system to switch between different orbits at will. !16
