Computing and Controlling Basins of Attraction in Multistability Scenarios

الملخص EN

The aim of this paper is to describe and prove a new method to compute and control the basins of attraction in multistability scenarios and guarantee monostability condition.

In particular, the basins of attraction are computed only using a submap, and the coexistence of periodic solutions is controlled through fixed-point inducting control technique, which has been successfully used until now to stabilize unstable periodic orbits.

In this paper, however, fixed-point inducting control is used to modify the domains of attraction when there is coexistence of attractors.

In order to apply the technique, the periodic orbit whose basin of attraction will be controlled must be computed.

Therefore, the fixed-point inducting control is used to stabilize one of the periodic orbits and enhance its basin of attraction.

Then, using information provided by the unstable periodic orbits and basins of attractions, the minimum control effort to stabilize the target periodic orbit in all desired ranges is computed.

The applicability of the proposed tools is illustrated through two different coupled logistic maps.
