Local ensemble transform Kalman filter, a fast non-stationary control law for adaptive optics on ELTs: theoretical aspects and first simulation results

Morgan Gray, Cyril Petit, Sergey Rodionov +4

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 t…

Local Ensemble Transform Kalman Filter: a non-stationary control law for complex adaptive optics systems on ELTs

Morgan Gray, Cyril Petit, Sergey Rodionov +3

We propose a new algorithm for an adaptive optics system control law which allows to reduce the computational burden in the case of an Extremely Large Telescope (ELT) and to deal w…
