设计了一种基于离散时间自适应近时间最优控制算法(DANTOC)的托卡马克等离子体垂直位置非线性控制器，以使系统稳定并最大化可保证稳定的状态空间区域。该控制器对晶闸管电源产生的边沿局域模式(ELM)和600赫兹噪声也具有很强的抗干扰性，这些噪声是干扰和测量噪声的主要来源。对JET托卡马克装置进行了仿真测试，结果证实了该控制器对不同等离子体构型的垂直位置控制的有效性。该控制器还在真实托卡马克COMPASS-D上进行了实验测试，结果表明，在存在干扰和测量噪声的情况下，该控制器相对于简单的线性PD控制器具有更好的性能。重点是设计方法论的发展。
A nonlinear controller for the plasma vertical position in a Tokamak, based on a discrete-time adaptive near time optimum control algorithm (DANTOC) is designed to stabilize the system and to maximize the state-space region over which stability can be guaranteed. The controller is also robust to the edge localized modes (ELMs) and the 600 Hz noise from the thyristor power supplies that are the primary source of disturbances and measurement noise. The controller is tested in simulation for the JET Tokamak and the results confirm its efficacy in controlling the vertical position for different plasma configurations. The controller is also tested experimentally on a real Tokamak, COMPASS-D, and the results demonstrate the improvement with respect to a simple linear PD controller in the presence of disturbances and measurement noise. The emphasis of the is on the development of the design methodology.
