Scientific paper

A kind of real-time adaptive control (RTAC) algorithm that can be put into practice in the feed-back close loop AO system was introduced in this paper. The RTAC algorithm, doesn't like the traditional control algorithm, considered the effect of atmospheric turbulence and the measurement noise together with the dynamic characteristics of the AO system. The parameters of controller can be modified during iterative calculation through the RTAC algorithm. The RTAC algorithm can adapt to the changes of work conditions to keep achieve optimal control performance. The theory of the RTAC algorithm will be discussed. The computer simulation and the experiment results on a modular adaptive optics experiment system with the RTAC algorithm will be discussed.
