|Abstract : Further space exploration in the far-infrared requires larger telescopes, in order to improve the spatial resolution of captured images. To this purpose, several conceptual designs future space telescopes are currently under study. One of them consists of a large deployable mirror, controlled by cables in tension. The objective of this project is to develop a strategy to control the shape of the primary mirror and damp actively structural vibrations with active cables. Such a strategy has already been successfully applied to future particle collider and gravitational wave detectors.
The project will include the development of a simplified model of this telescope, using lumped masses connected by springs, which will be used to elaborate control strategies. Then, the strategy will be applied on a more realistic model of the telescope. The final objective is to validate experimentally the control strategies on a scaled set-up of the telescope structure.
