基于CompactRIO的HL-2A环向场电流控制

Current Control of HL-2A Toroidal Field Based on CompactRIO

基于LabVIEW图形化编程语言,以NI公司PAC产品系列中的CompactRIO为硬件平台,研制出一套适用于脉冲工作模式的励磁调节器。该调节器以工业PC作为上位机,由嵌入式系统构成下位机,实时监测和控制每一次等离子体放电期间的工作状态。利用数字式增量PID算法对环向场电流进行反馈控制,控制周期为1ms。实际运行结果表明:研制的调节器具有控制精度高、稳定可靠等优点。

An excitation regulator capable of pulsed operation mode was developed using LabVIEW graphical programming language and NI CompactRIO. The excitation regulator including industnal PC as host computer and embedded system as slave computer was able to monitor and control the system working state during discharging in real time. The digital incremental PID algorithm was used to feedback control the toroidal field current with a control period of 1 ms. Actual operation results showed that the regulator had the advantages of high control precision, stability and reliability.
