要約(英語): This paper considers the compensation of flow disturbance, which is the variation of air pressure supplied by the air compressor of pneumatic active anti-vibration apparatuses (AVAs). Since the air pressure varies periodically, repetitive control is utilized for the suppression of the vibration induced by the flow disturbance. As the constant gain of the repetitive controller increases, disturbance compensation is improved further. On the other hand, when the gain becomes large, transmissibility increases in the frequency region including the mechanical resonance of AVAs. It leads to the performance degradation of the vibration isolation. In order to overcome the trade-off between the disturbance compensation and the transmissibility, a notch filter is employed instead of the constant gain in the repetitive controller. The center frequency of the filter is set to the frequency region including the mechanical resonance of AVAs so as to avoid the increase of the transmissibility. By using the proposed method, the performance of disturbance compensation can be improved without increasing the transmissibility. Furthermore, effects of parameters for the notch filter are investigated. Experimental and simulation results show that the performance of flow disturbance suppression and the transmissibility of the AVA are almost same regardless of parameters in the notch filter.
