Math Trick for Velocity in state-space models

Document #:

LIGO-T1400023-v1

Document type:

T - Technical notes

Abstract:

We do a derivation which allows us to model an isolation system with damping, and only track the input from ground displacement, while including the effects of input ground velocity
