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.
