摘要
近年来,光子变频技术成为了一个突破现有微波信号变频的关键性能指标的研究热点。然而,光子变频固有的工作状态不稳定,致使该技术难以实用化。设计了一种针对单一电光外调制器的光子变频控制系统,专门用于实现光子最佳变频工作点漂移后的快速、精准和微扰动地回归。该系统利用软硬件的综合优势,通过微积分算法提取光子变频工作点的微变参量,采用控制变量的比例算法使漂移工作点快速、微扰动地回归最佳变频工作点。
In recent years,photon frequency conversion technology has become a research hotspot that breaks through the key performance indicators of microwave signal frequency conversion.However,the inherent working state of photon frequency conversion is not stable,which makes the technology difficult to be applied.A photon frequency conversion control system for a single electro-optic external modulator is designed,which is specially used to realize the fast,accurate and micro disturbance regression after the best photon frequency conversion working point drifts.The system takes advantage of the comprehensive advantages of hardware and software,extracts the micro variable parameters of the photon frequency conversion working point by the calculus algorithm,and returns the drift working point to the best frequency conversion working point quickly and with micro disturbance by the proportion algorithm of control variables.
