Zonal multi-layer predictive control for multi-conjugate adaptive optics: Mavis simulations

Abstract

MAVIS (MCAO-Assisted Visible Imager & Spectrograph) is a proposed instrument for ESO’s VLT Adaptive Optics Facility. MAVIS aims at providing near-diffraction limited images across a 30” FoV. Predictive control allows an increased sky-coverage and is therefore attractive for use in the MAVIS application. This brief communication presents the problem statement, control law, estimation strategy, and simulations for one such scheme in the MAVIS context: a predictive zonal minimum-variance linear quadratic Gaussian controller based on the frozen-flow hypothesis.
