![]() ![]() Representative results illustrate TMT performance scaling with parameters, but the emphasis is on the modeling framework itself. for control of focus-mode, and sensor calibration. TIO is a non-profit international partnership among the California Institute of Technology, the University of California, the National Institutes of Natural Sciences of Japan, the Department of Science and Technology of India, and the. On Earth there are telescopes far larger the Very Large Telescope in Chile has an 8.2-meter mirror, whereas the twin Keck Telescopes in Hawai’i are each a gargantuan 10 meters wide. Models are used to predict the dynamic response due to wind and vibration disturbances, estimate achievable bandwidth in the presence of control-structure-interaction (CSI) and uncertainty in the interaction matrix, and simulate and analyze control algorithms and strategies, e.g. The Thirty Meter Telescope is being designed and developed by the TMT International Observatory LLC (TIO). We focus here on the development and validation of a suite of quasi-static and dynamic modeling tools required to support the design process, including robustness verification, performance estimation, and requirements flowdown. ![]() The higher bandwidth and larger number of segments compared with the Keck telescopes requires greater attention to modeling to ensure success. The Thirty Meter Telescope primary mirror is composed of 492 segments that are controlled to high precision in the presence of wind and vibration disturbances, despite the interaction with structural dynamics.
