Abstract
This paper proposes a control design method for stabilizing a chaotic signal of a non-linear system to a periodic signal. The underlying ide a of the method is the cancellation via feedback control of the subhar monic components of the considered signal. The resulting feedback cont rol scheme possesses a high degree of robustness against system uncert ainty and requires a very low control effort. A detailed application t o a CO2 laser with modulated losses is developed to illustrate the pro posed control design technique. (C) 1997 Elsevier Science Ltd.
