Plasma feedback control system of HL-2M tokamak

通过对HL-2M装置极向场线圈的参数和初始等离子放电控制需求的分析,基于实时采集系统和反射内存实时数据传输的先进控制集成技术,完成了整个HL-2M初始等离子体放电反馈控制系统的设计。新系统实现了稳定的1ms控制周期和实时数据传输,同时解决了实时控制周期和数据传输的延迟。实验结果表明新设计的等离子控制系统能满足初始等离子体极向场线圈电流控制的需求。

Through the analysis of the parameters of the poloidal field(PF)coils and the control requirements of the first plasma discharge on HL-2 M tokamak,the advanced control integration technology based on the real-time system and reflection memory(RFM)is adopted to design the first plasma control system(PCS)on HL-2 M device.The new system realizes the stable 1 ms control period and real-time data transmission and solves the real-time control period and data transmission delay.The experimental results show that the new PCS can meet the current control requirements of PF coils for the first plasma.
