Abstract

This paper considers a control scheme for the suppression of pneumatic isolation table's fluctuation induced by switching of the feedforward controller. The table acceleration and feedforward paths are added and the combined signal is sent to a damping integrator and gain. The damping integrator, besides generating a damping signal from acceleration signal, also avoids a large jump/drop of the feedforward signal during switching of the feedforward controller. Performance of this control scheme is evaluated by experiments while comparing with conventional control schemes. In addition, retuning of the feedforward compensator's gains is investigated. Based on the experimental results, it is shown that this control scheme can suppress both flow disturbances and switching of the feedforward controller.
