Adaptive Optics System

Adaptive Optics is a developing technology which is commonly used in ground-based astronomical telescopes. To achieve high-resolution imaging of targets in space, it is very important to reduce the effects of atmospheric turbulence. In this paper, we presented a simple and practical robust compensator for an AO system, based on the Robust Model Matching Strategy. Simulation and experimentation results show that the system with the robust controller has improved considerably comparing to the previous work.
