Abstract

For real-time feedforward control of an opto-mechanical piezo driven correction device using acceleration measurements, we model the Large Binocular Telescope's optical path using a linear dynamical system approach. The model is derived from experiments conducted at the telescope. These experiments will briefly be described and measurements along with simulation results will be presented. For off-site lab testing, a small experiment setup is described and experimental lab data is compared to the data taken at the Large Binocular Telescope in order to validate the lab setup's ability to reproduce the relevant dynamics of the telescope. Some early results of the lab setup are given as well.
