摘要

极端形状控制器(XSC)最初设计用于控制JET平顶阶段等离子体的形状,此时等离子体电流具有恒定值。在JET 2012实验活动中,XSC被用于改善等离子体电流上升和下降瞬态阶段的形状控制。为了避免这些暂态相位导致执行器饱和,设计并实现了一种限流避免系统。本文讨论了CLA算法,并给出了2012年在JET上使用XSC获得的实验结果。

Shape control with the XSC during plasma current ramp-up and ramp-down at the JET tokamak
The eXtreme Shape Controller (XSC) has been originally designed to control the plasma shape at JET during the flat-top phase, when the plasma current has a constant value. During the JET 2012 experimental campaigns, the XSC has been used to improve the shape control during the transient phases of plasma current ramp-up and ramp-down. In order to avoid the saturation of the actuators with these transient phases, a Current Limit Avoidance system (CLA) has been designed and implemented. This paper discusses the CLA algorithm and presents the experimental results achieved at JET during the 2012 campaigns using the XSC.
