针对托卡马克装置中等离子体密度控制系统进行了分析和研究，在此基础上采用新的数据采集卡和智能密度控制方法搭建了J-TEXT托卡马克装置上的密度反馈控制系统，进一步提高了系统的实时性和稳定性。通过等离子体密度对象的机理模型，基于神经内分泌调节器的原理，设计了一种带超短反馈的智能控制器，并对其在J-TEXT托卡马克装置的等离子体密度控制系统中应用进行研究。通过神经内分泌智能控制器对密度反馈控制系统中的PID控制参数进行优化，使得系统能在放电过程中根据密度状态实时在线修正PID参数。仿真结果显示，较常规PID而言，该方法综合提高了控制系统的性能，为托卡马克等离子密度智能控制系统的研制提出了新思路。

It mainly analyses and studies on Tokamak plasma density control system .We use a new data acqui-sition card as well as a new intelligent density control method to build the density feedback control system on Tokamak so that we can enhance the system's real-time performance and its stability .Based on the mechanism model of the plasma density along with the neuroendocrine regulator principle , we design an intelligent control-ler with an ultra-short feedback link inside , and study its application on the J -TEXT Tokamak plasma densi-ty control system .We use neuroendocrine theory to design a kind of intelligent PID in area of density control for controlled nuclear fusion .This makes the parameters of PID of control system can be adjusted on -line in real time during the experiment .The simulation results show that the proposed method , compared to the convention-al PID control method , can synthetically improve the performance of the control system .It makes contribution to the development of intelligent control system of Tokmak plasma density .
