To realize Tokamak plasma stably discharge for a long time needs to effectively control plasma density. In this paper, the authors through analyzing the current Tokmak plasma density control system, they put forward a solution of optimization for the original system from the aspects of density data acquisition and control algorithm, they use PCI DAQ2010 data acquisition card to design the high-speed data acquisition channel, and apply the acquisition channel in the density feedback control system. And, they propose a plasma density intelligent controller based on neuroendocrine PID, which can adjust parameters online according to the real-time density state in the discharge process.
