Abstract

Specialized control structures can be used to reduce the computational burden of determining the control at each frame. The parameters that define these controllers are chosen to maximize performance. The optimization of the parameters is more efficient if gradient information is available. This paper presents the gradient calculation for an arbitrarily parameterized controller of an adaptive optics system. The gradients are then specialized to modal gain and proportional-plus-integral controllers.
