FreeGSNKE脉冲设计工具（FPDT）：用于演化型等离子体情景与控制设计的计算框架
摘要
我们提出FreeGSNKE脉冲设计工具（FPDT），一个开源、基于Python的计算框架，使能够进行silico测试和预测性设计托卡马克等离子体情景和控制策略。FPDT将FreeGSNKE演化平衡求解器与包含模块化和可定制控制器的虚拟等离子体控制系统（PCS）耦合在内。给定一组用户定义的波形和控制参数，虚拟PCS利用反馈和前馈控制来调制等离子体电流、位置和形状，同时遵守多极场电流和电压的机器安全限制。 resulting framework allows simulation of the controlled dynamic evolution of plasma equilibria, along with the currents in both active poloidal field coils and passive conducting structures, under the assumption of axisymmetry. The FPDT can be used to develop plasma scenarios, test control schemes, calibrate control parameters, and perform uncertainty quantification studies, thereby reducing iterative and expensive experimental testing on a physical tokamak. The FPDT is machine-agnostic and can be customised to implement different control algorithms tailored to the specific tokamak of interest. Here, we outline the overall framework and validate its performance on plasma discharges on the MAST Upgrade tokamak in the `flat-top' phase. We demonstrate excellent quantitative agreement between the FPDT simulations, the desired control waveforms, and the experimental shot data. With this extension to the FreeGSNKE open-source suite of codes we aim to encourage more reproducible and collaborative research in plasma modelling and control.
