摘 要: | 基于双光子吸收的飞秒激光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飞秒激光双光头三维光盘存储系统。本文针对DVD光学头进行了详细地分析,建立DVD光学头音圈电机电气模型,并根据电气模型计算得到传递函数。针对DVD光学头传递函数,通过最少拍无纹波控制算法,得到最优数字控制器表达式。

Abstract: | Femtosecond laser 3D optical storage based on two - photon absorption is an important method to achieve high - density optical storage. In order to improve the practical application of two - photon 3D optical storage technology, based on CD / DVD servo technology and two - photon absorption technology, the 3D disc storage system of two pick - up head is built. The DVD optical head is analyzed in detail, electrical model of DVD optical head' s voice coil motor is established, and in accordance with the calculation of the electrical model we can get transfer function. For transfer function of DVD optical head, by ripple - free deadbeat control algorithm, the optimal digital contmller expression is obtained. |
