| Popis: | In this paper we will discuss the application of optimal filtering techniques for the adaptive optics system of the LBT telescope. We have studied the application of both Kalman and H$_\infty$ filters to estimate the temporal evolution of the phase perturbations due to the atmospheric turbulence and the telescope vibrations on tip/tilt modes. We will focus on the H$_\infty$ filter and on its advantages and disadvantages over the Kalman filter. 6 pages, 6 figures, 3 tables, European Control Conference (ECC) 2009, Budapest, Hungary, August 23-26, 2009 |
