摘要

Optical systems such as telescopes are very complex, and their model usually with the uncertainty. To deal with the uncertainty of adaptive optics system and improve system robust stability, the mixed sensitivity H_∞ control has been introduced to design system controller, In order to testify the validity, wavefront aberration correction capability as well as the robust stability has been compared between the mixed sensitivity H_∞ controller and the classic integral controller. The computer simulation results demonstrate that the system with the mixed sensitivity H_∞ controller, while can't guarantee a better correction performance, has greater robust stability than the one with the classic integral controller. That is to say, greater robust stability is achieved at the expense of the correction capability in the system with H_∞ controller. Moreover, the greater the uncertainty is, the more proceeds the mixed sensitivity H_∞ controller will produce. It proves the efficiency of the mixed sensitivity H_∞ controller in dealing with the uncertainty of adaptive optics system.
