论文摘要
在本文中，我们提出了基于Extremum Seewing（ES）算法的Tokamak等离子体的垂直稳定〜（VS）控制系统。提出的策略的要旨是在控制动作中注入一个振荡术语，并利用修改的ES算法，以使等离子体的平均运动沿不稳定模式的平均运动为零。这样，可以实现等离子体的不稳定垂直动态的稳定。该方法通过整体〜ITER TOKAMAK磁控制系统的线性和非线性仿真验证，目的是在放电的整个扁平阶段证明强大的操作以及对各种干扰的反应能力。
In this paper we propose a vertical stabilization~(VS) control system for tokamak plasmas based on the extremum seeking (ES) algorithm. The gist of the proposed strategy is to inject an oscillating term in the control action and exploit a modified ES algorithm in order to bring to zero the average motion of the plasma along the unstable mode. In this way, the stabilization of the unstable vertical dynamic of the plasma is achieved. The approach is validated by means of both linear and nonlinear simulations of the overall~ITER tokamak magnetic control system, with the aim of demonstrating robust operation throughout the flat-top phase of a discharge and the capability of reacting to a variety of disturbances.
