摘　　要：双光子三维光存储是实现高密度光存储的重要方法。为了提高双光子三维光存储技术的实用化,基于CD/DVD伺服技术和双光子吸收技术搭建了一套双光头三维光盘存储系统。针对CD/DVD光学读取头传递函数,采用常规PID控制系统,构建PID控制系统仿真的模型,并进行PID参数的整定,合理地选取了PID控制器的比例、积分和微分系数分别为2、0.03和0.02,使系统的稳定性、响应速度、超调量和稳态误差均可达到系统性能指标的要求。Two-photon 3D optical storage is an important method to achieve high-density optical storage. In order to make two-photon 3D optical storage technology more practical, based on CD / DVD servo technology and two-photon absorption technology, the 3D disc storage system of two pick-up head was built. Refer to the transfer function of the CD/DVD pick-up head, the authors used conventional PID control system, built simulation model of PID control system and tuned PID parameter. The system legitimately selected the proportion, integral and deriviative parameters of the PID control system to be 2, 0.03 and 0.02 respectively, that make the stability, the speed of response, the overshoot and steady state error of the system reach the requirements of the system performance.
