Abstract

In this paper we present preliminary experimental results relative to the control of multistage seismic attenuators and inertial platforms in the band 0.01±10Hz, using open loop monolithic folded pendulums as inertial sensors. In fact, beyond the obvious compactness and robustness of monolithic implementations of folded pendulums, the main advantages of this class of sensors are the tunability of their resonance frequency and their high sensitivity over a large measurement band. The results are presented and discussed in this paper together with the planned further developments and improvements.
