Abstract

In this paper we present experimental results about preliminary activity related to the control of seismic attenuators and inertial platforms using monolithic accelerometer sensors based on folded pendulum mechanical scheme. Apart the compactness and robustness of monolithic implementations of folded pendulums, the main advantages of this kind of sensors are the tune-ability of their resonance frequency and their high sensitivity over a large measurement band. In this preliminary test we show that the main resonant frequencies of the inertial platform, located in the frequency band 0.01 ± 10Hz, can be controlled using open loop monolithic folded pendulums as inertial sensors. The results are presented and discussed in this paper together with the planned further developments and improvements.
