Abstract
The fastness and robustness of a control algorithm are highly important in the performance of
adaptive optics systems. The proportional-integral-derivative control with arranging the transient process,
which is designed using a tracking differentiator, is applied into an adaptive optics system. This control
algorithm greatly improves the dynamic properties of the control system. To identify the underlying reasons
for these improvements, the influence of the control algorithm is theoretically discussed. The control
algorithm is verified by a simple adaptive optics system for tip/tilt correction. The experimental results
demonstrate that the control algorithm is fast and robust.
