Abstract / Description:We dynamically model the Large Binocular Telescopes optical path using a linear system approach. The model is derived from experiments conducted at the telescope. These experiments will be described and we will explain the possibilities and difficulties in extracting a simulation model from measured data. The model also incorporates disturbances, such as wind forces and single excitations induced by vibrating machinery. We will show, why it is necessary to measure structural vibrations at the LBT and why we follow a model based approach in estimating the mirror’s oscillatory motions. Some simulation results will be presented and compared to measured time series and a conclusion will be drawn. An outlook will be given on how the observer can be implemented.
