多级数字光圈控制器的设计和实现

Design and Implementation of Multilevel Digital Iris Controller

本文介绍了一种基于AVR单片机的数字胃肠造影系统光圈控制器的设计和实现。该控制器以单片机为核心,以PID控制理论为思想,通过外围硬件电路来达到控制目的。通过串行端口实时调整光圈大小,该光圈控制器具有响应速度快、控制精度高和稳定性好等特点。在实际运行中效果良好。

This article describes the design and implementation of the iris Controller in a Digital Gastrointestinal Imaging System based on AVR Processor.The author designed a peripheral circuits based on Atmega32 in terms of PID control theory.According to real-time adjusting, the Controller has an outstanding performance in fast response、high accuracy and long-time stability.
