Control of an Air Type Anti-Vibration Apparatus with Two Degrees-of-Freedom

Shift of Characteristic with Integral Acceleration Feedback

Abstract

In the field of vibration control, the acceleration sensor is widely used as a vibration sensor for large-scale structure and soft ground. It is preferable to be able to use the velocity and displacement additionally. Then, the absolute velocity and displacement sensors are proposed, and they can be used as FB sensors. Up to now, the research, which is about each signals' FB to an air type anti-vibration apparatus with one degree-of-freedom using an absolute displacement sensor, has been experimented. Comparing to this research, the apparatus with two degrees-of-freedom will be controlled, and the applications of the absolute displacement sensors are verified in this paper.
