基于TMS320F2812 DSP的Focus控制器设计

Design of the Focus Controller Based on TMS320F2812 DSP

借用原有DVD-ROM的机械机构、驱动单元、光学单元,以TMS320F2812 DSP芯片为核心控制器,搭建了DVD的Focus控制实验平台;分别从硬件和软件两方面进行设计,从而对前期采用PID算法设计的Focus控制器进行了可行性验证。

The thesis takes the TMS320F2812 DSP chip as the core controller, establishes a DVD Focus controlling experimentation platform which is based on the mechanism, the driving unit and the optics unit of the primary DVD-ROM. From the two aspects of hardware and software to design the controller, we validate the feasibility of the Focus controller designed by the PID algorithm in prophase.
