Receding-Horizon Adaptive Control of Aero-optical Wavefronts

This paper introduces a new method for adaptive prediction and correction of wavefront errors in adaptive optics. The new method is based on receding-horizon control design and an adaptive lattice filter. Experimental results presented in the paper illustrate the capability of the new adaptive controller to predict and correct aero-optical wavefronts derived from recent flight-test data. The experimental results compare the performance of the new adaptive controller the performance of a minimum-variance adaptive controller previously used in adaptive optics. These results demonstrate the reduced sensitivity of the receding-horizon adaptive controller to high-frequency sensor noise.
