摘要

This paper reports on a six-axis vibration isolator for space applications. It is divided into three parts. The first part recalls the principles of active isolation and summarizes the main theoretical results for multiple-axis decentralized control based on force feedback. The second part discusses the technology and describes the evolution of the design over the five years of this project. The third part is devoted to the performance evaluation; zero-gravity tests in parabolic flight are reported: the isolator is proved efficient in a frequency band between 5 Hz and 400 Hz, with a maximum attenuation of -40 dB between 50 Hz and 200 Hz.
