本文简述了用位移做反馈控制信号,用非线性二位调节器组合前馈环节,控制厚钢壳(厚度d=5cm)外的垂直场和水平场线圈电流,在HL-1装置上实现了等离子体位置反馈控制的情况。当铁芯不饱和时,在水平和垂直两个方向上均可控制等离子体位置在±2mm之内。
In this paper, the displacement feedback control signal is briefly introduced. A non-linear two-position regulator is used to control the vertical field and the horizontal field current outside the thick steel shell (thickness d = 5cm) Plasma position feedback control of the situation. When the core is not saturated, the plasma position can be controlled within ± 2mm in both horizontal and vertical directions.
