Abstract:

This document is brief summary of the Type A suspensions control status.
Here we report:
1) the diagonalization procedure of LVDTs and the actuators of IP and BF;
2) the calibration and diagonalization of the inertial sensors;
3) the estimation of the intrinsic noise of these sensors;
4) the blending technique and a preliminary tuning of the blending frequency applied to ITMX.
5) the performance of a preliminary version of inertial control on ITMX.
