Wind Evaluation Breadboard Control Architecture, Dynamic Model and Performance

The WEB (Wind Evaluation Breadboard) for the European ELT (Extremely Large Telescope) Design Study is a primary mirror and telescope simulator formed by seven segments, including position sensors, electromechanical support systems and support structures. The purpose of the WEB is to study the effects of wind on the control of the positions of the segments. This paper describes the control architecture, the dynamic model generated based on the Finite Element Model and the performances achieved in simulations.
