Method of vibration control of a structure by combining auto-tuning control of anti-resonance and optimal vibration absorbers

摘要

The vibrations of a structure having a vibration absorber without damper vanish at the anti- resonance frequency theoretically. Hence if the rigidity of the absorber is controlled to produce and anti-resonance state according to the forced frequency, the vibrations of the structure can be detected for sinusoidal forces. However, external vibration force involves higher modes, in general, so the structure is excited by various frequencies.
