Abstract

An ultra-low frequency Pre-Isolator (PI) has been built for micro-seismic noise isolation and the excitation reduction of suspension chain resonant mode amplitudes, A multidimensional control system, based on Digital Signal Processing (DSP), has been developed for position control and normal mode damping of the PI. In this paper we demonstrate the successful control of the suspension system.
