Controlling phase multistability in coupled period-doubling oscillators.

A simple method of switching between coexisting attractors in two coupled period-doubling oscillators is proposed. It is based on "pulling" phases of oscillations into suitable value by means of two periodic forces which simultaneously influence the both sub-systems. The frequency and the phase-shift of the forces are key parameters of the control. Their choice determines the resulted regime. The method is tested on example of coupled Chua's oscillators and exhibits its efficiency both for periodic and for chaotic attractors.
