HL-2A装置脉冲发电机励磁控制系统

Excitation control system of pulse generator on HL-2A tokamak

采用增量式PID控制算法和基于FPGA的相移数字触发器组成的励磁反馈控制系统实现对HL-2A装置脉冲发电机输出的控制,并通过基于西门子PLC构成的逻辑控制系统保护励磁系统的安全。实际运行结果表明,该励磁控制系统具有控制精度高、运行稳定可靠的优点。

The HL-2A pulse generators outputs are controlled by their excitation feed back control systems, which adopt PID algorithm and the phase-shifted digital trigger circuit based on FPGA （field programmable gate array）, and the safety of the excitation system is protected by Siemens PLC logic control system. The actual operation results show that these excitation control systems have high control precision, stable and reliable advantages.
