【摘要】 稳定、可靠、可重复的等离子体电流及位移控制对于托卡马克装置进行物理实验至关重要。本文的主要工作是建立J-TEXT托卡马克等离子体电流及位移反馈控制模型,基于此模型及J-TEXT装置参数建立等离子体电流及位移反馈控制系统。该系统分为测量环节、现场采集环节、逻辑运算环节和控制输出环节。采用该系统,已成功产生并维持超过200kA的等离子体电流,在电流平顶阶段,等离子体电流水平位移及垂直位移均控制在1cm内。系统的稳定性、可靠性及可重复性好,已达到装置现阶段物理实验运行需求。更多还原

【Abstract】 A stable,reliable and repeatable plasma current and position control are very crucial for a tokamak device conducting the physics experiment.The major work of this article is a feedback control model,which is set up for plasma current and position control.Based on this control model,a plasma current and position feedback control system is built up. The system consists of measuring segment,data acquisition segment,logic calculation segment and control output segment. An up to 200-kilo-ampere plasma is generated and maintained by this system.The horizontal and vertical displacement of the plasma current can be controlled within one centimeter in the flat top of the current.The stability,reliability and repeatability of the system are sufficient for the need of present physical experiment.更多还原
