基于自动控制理论的自适应光学控制系统优化
Optimization of adaptive optical control system based on automatic control theory
摘要
Abstract
In order to improve the working speed of adaptive optics as soon as possible , the algorithm of automatic control theory was applied for adaptive optical system without changing the characteristics of the hardware .After analyzing the close-loop control system of the adaptive optical system , the mathematical model of adaptive optical control was constructed . The controllers and the control algorithms were designed and their characteristics were discussed based on the automatic control theory .After combining the automatic control algorithms and human eye wave-front aberration correction , the control algorithm was applied to the aberration correction .The experiment result shows that the Smith estimating precompensation control has higher closed-loop bandwidth, better dynamic and steady state characteristics than proportion-integration ( PI) control and integrator control .The result of the Smith estimating precompensation control has better speed in static aberration correction of the bogus mode eye and makes the root mean square least in the dynamic aberration correction of human eye .So the Smith estimating precompensation control can optimize the control system of adaptive optics .关键词
