摘要

本文介绍了一种应用于离子源进气量控制的实时反馈控制系统。系统采用A/D模数转换和D/A数模转换卡完成系统数字信号处理的输入与输出。系统的控制程序采用Linux内核支持的RTLinux实时操作系统作为底层操作系统并进行了适当优化裁剪

获得了适合系统控制要求的实时控制程序开发环境

并应用了灵活控制实验中离子源进气量的控制算法。实验首次获得离子源4.5s稳定放电的实验结果。

Abstract

A real-time feedback control system (RFCS) which is applied to control the gas supply of the ion source is introduced in this paper. The system consists of an A/D data acquisition card and a D/A output card

which are used as the data input and control output of the digital signal processing system. RTLinux OS which is compatible with the Linux kernel is adopted by the control application. The RTLinux is also optimized to reduce the size and provides good program developing environments and fulfills the control requirements. A flexible control algorithm is introduced to control the gas supply of the ion source. By the RFCS application

the experiment has firstly got the longest pulse by far: a stable discharging of the ion source lasting for 4.5s.
