本文以液靜壓軸承油膜厚度保持不變化及全體油膜均一為研究目標，探討控制排量泵轉速之流量控制法則解決膜厚不均勻及膜厚隨負荷而變的問題，以軸承承載件上四個點之位移、流量作為回饋信號，並建立液靜壓軸承次系統的控制方法。本文以LabView軟體建立感測與控制的人機介面，以感測回饋進行計算程式並控制馬達轉速，達到等膜厚控制。

In this paper, hydrostatic bearing oil film thickness to maintain a uniform film does not change and all research and development goals, discuss controlling the flow speed of the displacement pump control laws to solve uneven film thickness and the film thickness becomes a problem with the load to the bearing carrier four displacement of a point, as the feedback signal flow and establish control methods hydrostatic bearing sub-systems. In this paper,LabView software to establish the sensing and control of man-machine interface to sense feedback and calculated program to achieve and so the film thickness control.
