Identification, Prediction and Control of Aero Optical Wavefronts in Laser Beam Propagation

摘要

This paper describes linear time-invariant optimal prediction and control of aero-optical wavefronts derived from recent flight-test data. The optimal controller is based on an optimal prediction filter that has the form of a multi-input-multi-output state-space model that captures the statistics of the aero-optical wavefront sequence. Experimental result in the paper show the improvement in wavefront correction achieved by an optimal controller based on the identified prediction filter, as opposed to a classical adaptive optics loop.
