Abstract

This paper focuses on the design of the control system of massively actuated deformable mirrors for astronomical adaptive optics applications. The proposed solution is based on a high-frequency completely decentralized feedback combined with a hybrid low-frequency term, which is the sum of feedforward-feedback contributions. An appropriate in the field system identification procedure and an automatic gain optimization eventually lead to a complete self-tuning controller. The improvements of system performances are evaluated through high-fidelity simulations.
