Study on Active Vibration Isolation System - Design of Control System -

抄録

The possibility of realizing an excellent microgravity environment is one of the most important features that attract experimentalist toward space. A difficulty encountered in this connection is that there exist a multitude of acceleration disturbances in thespacecraft which recent research has shown to significantly affect certain experiments such as those on diffusion and crystal growth phenomena, and on fluid behavior. In order to reduce acceleration disturbances, an active vibration isolation system is proposed, which should serve in providing an excellent microgravity environment. The experimental equipment is supported without contact eith the spacecraft structure, by means of electromagnetic suspension and PID controller. The design of the conrtol system and numerical simulations to verify system performance have been conducted.
