Paper Abstract

The Keck I and II telescopes have been operational respectively since 1990 and 1996. Operational improvements are sought to decrease the settling time in response to short moves. The structural response of the open loop system has been re-identified and the mount control design has been re-examined. Changes to the mount control compensators and command shaping architecture have been proposed in order to achieve improved response. Results from these studies are presented, both theoretical and experimental.
