| 摘 要： | 在校正大气湍流畸变信号的自适应光学系统中，基于大气开环数据，对采用最小递归二乘RLS算法预测复原电压以减小自适应光学系统中的时间伺服延迟进行了仿真研究。并与未采用预测时的误差进行了比较，对比结果表明：采用RLS算法后，可以有效的降低系统由伺服延迟引起的误差。

| Abstract: | In adaptive optic system,for correcting the atmosphere turbulence,base on the open-loop atmospheric data,a kind of prediction control algorithm was proposed in this paper to reduce the effect of servo lag.The spatio-temporal recursive least square(RLS) prediction algorithm was used to predict the deformable mirror.The residual error of the adaptive optics system was calculated with and without the prediction control algorithm respectively.The results show that the residual error was reduced effectively with the RLS algorithm. |
