Experimental results are reported concerning the possibility of reducing and even suppressing chaoticity in a bistable magnetoelastic beam system by means of parametric periodic perturbations. The experimental parameters are chosen such that a strange attractor is observed. Then a parametric perturbation is added. When its frequency approaches some resonant value, laminar phases are observed of increasing duration up to complete regularization of the motion at exact resonance.
Fronzoni et al. (Sat,) studied this question.
