The structure and control method of the plasma horizontal position equilibrium control system in the HT-6M Tokamak have been analyzed theoretically. A high power GTO chopper and the Bang-Bang control method are used and a good result is Obtained. 在理论上系统地分析了HT-6M托卡马克等离子体水平位移平衡控制系统的结构及其控制方式,并采用大功率GTO斩波器作为反馈场电源和Bang-Bang控制模式的技术,取得了较好的效果。
