Abstract
This paper proposes the control method for vibration caused by variation of air pressure supplied to pneumatic anti-vibration apparatuses. In this method, air pressure variation, i.e., flow disturbance is estimated offline. The time-series data of disturbance estimate is added to the control input signal. Smoothing is utilised to reduce the noise of estimated signal. Moreover, to compensate effects of time-lag of input, two kinds of a shaped signal are also utilised. Experimental results show the effectiveness of the proposed vibration suppression method.
