DIII-D先进托卡马克物理计划要求DIII-D等离子体控制系统具有极高的性能，包括同时精确调节等离子体形状、储存能量、密度和偏滤器特性，以及协调抑制磁流体动力学不稳定性。为了满足这些苛刻的控制要求，我们应用集成等离子体控制方法，包括基于物理的等离子体和系统响应模型的构建，对操作实验模型的验证，相互协调操作的集成控制器的设计，对离线和实际机器控制平台的控制动作的模拟，以及通过设计测试循环的迭代进行优化。本文介绍了DIII-D物理模型的建立、基于模型的新型等离子体控制器的研制和实验应用等方面的进展。我们还描述了超导EAST和KSTAR托卡马克的控制软件，硬件和基于模型的控制算法的发展。
The DIII-D advanced tokamak physics program requires extremely high performance from the DIII-D plasma control system, including simultaneous accurate regulation of plasma shape, stored energy, density and divertor characteristics, as well as coordinated suppression of magnetohydrodynamic instabilities. To satisfy these demanding control requirements, we apply the integrated plasma control method, consisting of construction of physics-based plasma and system response models, validation of models against operating experiments, design of integrated controllers that operate in concert with one another, simulation of control action against off-line and actual machine control platforms, and optimization through iteration of the design-test loop. The present work describes progress in development of physics models and development and experimental application of new model-based plasma controllers on DIII-D. We also describe the development of the control software, hardware, and model-based control algorithms for the superconducting EAST and KSTAR tokamaks.
