Description
The Wind Evaluation Breadboard (WEB) for the European Extremely Large
Telescope (ELT) is a primary mirror and telescope simulator formed by
seven segments simulators, including position sensors, electromechanical
support systems and support structures. The purpose of the WEB is to
evaluate the performance of the control of wind buffeting disturbance on
ELT segmented mirrors using an electro-mechanical set-up which simulates
the real operational constrains applied to large segmented mirrors. The
instrument has been designed and developed by IAC, ALTRAN, JUPASA and
ESO, with FOGALE responsible of the Edge Sensors, and TNO of the
Position Actuators. This paper describes the mechanical design and
analysis, the control architecture, the dynamic model generated based on
the Finite Element Model and the close loop performance achieved in
simulations. A comparison in control performance between segments modal
control and actuators local control is also presented.
