Abstract

This paper compares an optimal linear time-invariant controller and an adaptive controller for prediction and control of aero-optical wavefronts derived from recent flight-test data. Both control methods have the form of multichannel prediction filters that capture the statistics of the aero-optical turbulence to mitigate latency in the adaptive optics loop. Experimental results show the improvement in wavefront correction achieved by both prediction methods. Altering the flow characteristics of the disturbance wavefront during the control process illustrates the ability of the adaptive controller to track changes in the aberration statistics.
