Control for a Cryo Vibration Isolation Platform: Active vibration isolation in 3 degrees of freedom

Experiments in a closed-cycle cryostat suffer from vibrations caused by its pulse tube. To reduce this disturbance, a vibration isolator needs to be placed inside the cryostat. Since mechanical dampers do not work in a cryogenic environment, it requires active damping. This thesis is about the design of a controller for such an active vibration...
