Suppressing chaos in damped driven systems by non-harmonic excitations: experimental robustness against potential’s mismatches

Abstract The robustness of a chaos-suppressing scenario against potential mismatches is experimentally studied through the universal model damped, harmonically driven two-well Duffing oscillator subject to non-harmonic excitations. We consider second order analogous electrical circuit having an extremely simple that differs from standard model, and compare main theoretical predictions regarding latter with experimental results former. Our prove high regardless (constant) values remaining parameters. Specifically, inverse dependence regularization area in control parameter plane on impulse excitation as well minimal effective amplitude when transmitted maximum were confirmed.
