Abstract:

The design of the plasma density feedback control system (PDFCS) is described. The design requirements of the feedback control system including hardware and software are proposed to approach the plasma density reference value and then a discussion of “how to realize the feedback control” is given. The experimental results show that the feedback control system satisfies the real-time and stable control.

Key words: Plasma density, PID controller, H-mode
