摘要: Abstract The goal of this study is to demonstrate the capability actively isolate a platform from seismic vibrations using an interferometric inertial sensor. To purpose, homemade high-resolution uni-axial sensor (in vertical direction) developed and then integrated single-degree-of-freedom (SDOF) isolation system. A theoretical firstly performed in order better understand dynamics It found that suffers tilt-vertical coupling due influence gravity force if not perfectly aligned. By taking tilt into account, dedicated controller designed, seeking large vibration frequency band interest. Experiments are conducted for validating analysis examining performance. shows reduction transmitted motion up 60 dB range 0.1 Hz 10 Hz.
