Semi-active suppression of cable 1/2-order subharmonic resonance in a cable–beam coupled system using time-delayed velocity feedback

Key Points

• Subharmonic resonance was effectively suppressed, improving system stability and performance.
• Feedback control showed an effectiveness with a reduction in resonance amplitude up to 45%.
• Observation of a cable-beam coupled system revealed insights on the use of time-delayed velocity feedback.
• This approach may enable enhanced designs for structures vulnerable to resonance, offering broader applications.
