摘要翻译：
KTX（科达图尔实验）是中国科学技术大学的一个新的反向场箍缩装置。KTX独特的双C设计使得功率和粒子控制的修改和研究变得容易，但新设计中的狭缝区误差场不容忽视。本文的目的是介绍一种新的主动反馈控制系统，它可以改变独特的双C结构之间的电压，以使环形场更好。FPGA是整个系统的核心部分，能够实时处理和传输来自线圈的数据，对整个过程进行控制。该系统采用2个高速8通道ADC对16个Rogowski线圈的模拟信号进行转换，实现了铜壳垂直间隙附近动态涡流的检测。FPGA还通过命令16个高速DAC给RFP器件一个反馈，控制外部功率放大器改变独特的双C结构之间的电压。结果表明，该系统减小了KTX器件的误差场，实现了较低时延的快速矩阵计算。

英文摘要：
  KTX (Keda Tours eXperiment) is a new RFP (reversed field pinch) device at the University of Science and Technology of China. The unique double-C design of the KTX makes modifications and investigations of power and particle control easy, but the error field of slit zone in the new design should not be neglected. The objective of this paper is to introduce a new active feedback control system which can change the voltage between the unique double-C structures to make the toroidal field better. FPGA is the central part of the whole system to control all the process, because it can manipulate and transmit the data from coils in real time. There are 2 high-speed 8-channels ADCs in the system to convert the analog signal from 16 Rogowski coils which can detect dynamic eddy current of copper shells near the vertical gap. FPGA also control the external power amplifier to change the voltage between the unique double-C structures by commanding 16 high-speed DACs to give the RFP device a feedback. Result indicated that the error field in KTX device was reduced, and the system could successfully achieve fast matrix calculation with lower delay.
