Local ETKF for AO on ELTs
Added by Morgan GRAY about 4 years ago

We propose a new algorithm for an adaptive optics system control
law, based on the Linear Quadratic Gaussian approach and a Kalman
Filter adaptation with localizations. It allows to handle non-stationary
behaviors, to obtain performance close to the optimality defined with
the residual phase variance minimization criterion, and to reduce the
computational burden with an intrinsically parallel implementation on the
Extremely Large Telescopes (ELTs).
