The purpose of this study is to investigate effects of electro-magnetic control on the improvement of damping characteristics and prevention of self-excited vibration occurrence in the aerostatic guiding system by means of theoretical calculation and experiments. The results are as follows ; It is confirmed that in the stable region distinct improvement of logarithmic decrement is obtained, namely the improvement from 0.10 to 0.75 in the theoretical calculation and from 0.11 to 0.53 in the experiments. It is also confirmed that self-excited vibration occurred in the unstable region ceases during the time of 0.11 s in the theoretical calculation and 0.30 s in the experiments.
