Description
Adaptive optics (AO) system performance is hindered by the mechanical limits of the deformable mirror (DM), namely stroke limits, interactuator stroke limits, and mechanical resonance.The nature of the multi-in multi-out (MIMO) control system does not lend itself well to notch filters to combat the mechanical resonances, and the stroke limits introduce non-linearities to the system.The traditional method of ensuring stable AO performance is to provide sufficient gain margin (i.e. reduce the AO system bandwidth).Guidestar and UCLA are proposing a novel method of spatial filtering of the phase errors combined with innovative model predictive controllers and multi-channel adaptive filtering to optimize the control bandwidth within a spatial frequency domain.
