Abstract
We present the minimum variance control solution for an AO system featuring several NGS/LGS wavefront sensors operating at different sampling rates. We show that the optimal solution is based on a non-stationary Kalman filter. A simple sequential implementation is proposed, with one update equation per sensor. A stationary suboptimal solution is also derived.
