Abstract

The design of real time heat load protection functions for the ITER tokamak first wall (FW) plasma-facing components (PFCs) requires the development of simplified, but reliable control-oriented models. The dynamics of interest in this case encompasses slow changes in plasma shape or transient increases in wall power loading. For this purpose, this study presents a new lightweight framework for simulating the FW thermal response during a plasma discharge, validated against higher fidelity codes and developed in a MATLAB/Simulink environment specifically for rapid prototyping and testing of control schemes. This innovative tool allows the ITER FW heat load controller to be designed in the plasma control system simulation platform (PCSSP) following a model-based approach, where a dynamical model of the physical process to control is an integral part of the controller synthesis procedure.

基于模型的ITER首次壁面热负荷控制设计

ITER托卡马克第一壁（FW）等离子体面组件（pfc）的实时热负荷保护功能设计需要开发简化但可靠的面向控制的模型。在这种情况下，感兴趣的动力学包括等离子体形状的缓慢变化或壁功率负载的瞬态增加。为此，本研究提出了一个新的轻量级框架，用于模拟等离子体放电过程中FW的热响应，并在更高保真度的代码下进行了验证，并在MATLAB/Simulink环境中开发，专门用于快速原型设计和控制方案测试。这种创新的工具允许在等离子体控制系统仿真平台（PCSSP）中按照基于模型的方法设计ITER FW热负荷控制器，其中要控制的物理过程的动态模型是控制器合成过程的一个组成部分。
