Paper Abstract

In the context of adaptive optics (AO), Linear Quadratic Gaussian (LQG) control uses the state-feedback of the atmospheric distortion wavefront estimate. Such estimate is obtained from a Kalman filter which incorporates a model of the atmospheric distortion wavefront. We analyze the performance and the robustness of LQG- based control compared to classic integral control, by the means of end-to-end simulations and by considering different levels of wavefront sensor (WFS) noise.
