Abstract

The servo-loop components and control algorithm of the COME-ON project involved in imaging in the near-infrared range with a 4-m telescope are described. Attention is focused on the wavelength sensor, wavefront computer, control computer, high-voltage amplifiers, and deformable and tip-tilt mirrors. An interaction matrix and its modal decomposition are discussed, along with modal filtering and tip-tilt control. It is pointed out that the comparison between theoretical and experimental eigenmodes of the interaction matrix demonstrates the spatial modelization validity of the system.
