We propose an antiresonance enforced active vibration absorber system, in which the passive dynamic vibration absorber is weakly damped and tuned to the peak frequency of the vibration of the main mass and the optimally designed active control system with frequency shaped cost functional is added to enforce the antiresonance. This system is a variation of a hybrid vibration absorber but is more effective than the conventional one, particularly when the external exciting force is a harmonic wave or has a sharp peak in the spectrum. By means of a cross-correlation function, the system can automatically tune the antiresonant frequency to the peak frequency, and reduce the vibration effectively even when the peak frequency of the external exciting force changes. Also, we discuss the theoretical analysis of the system, including the digital realization and control stability. Finally, experimental results are given which show the effectiveness of the mechanism.
