摘要

摘要: 为提高托卡马克装置磁场电源的控制性能，实现对等离子体的先进控制，设计了基于LabVIEW RT和FPGA的磁场电源实时控制系统。根据等离子体控制对电源控制系统实时控制的要求，使用反射内存卡实现实时数据传输，应用实时操作系统来保证系统的确定性应用和系统的可靠性，采用NI 7813R系列数据采集卡实现对晶闸管变流器的控制。实验结果表明，该系统满足等离子体放电对电源控制系统实时性的要求，并具备较高的可靠性和稳定性。

Abstract: A high-performance real-time control system is designed for magnet power supply in tokomak, which is based on LabVIEW RT and field programmable gate array (FPGA) techniques. According to the real-time control requirements of the magnetic power supply, a reflective memory card was used to realize real-time data transformation, and a real-time operation system is applied to ensure the reliability and determinism of the power supply system. Then NI DAQ 7813R data acquisition card was used to control thyristor converter. The experimental results of the real-time control system for the power supply are presented, which demonstrate that the control system meets the design requirement and has high-reliability and determinism.
