CAREER: Nonlinear Control of Plasmas in Nuclear Fusion

ECCS-0645086E。该提案的目标是开发聚变等离子体反馈控制方面的综合研究和教育计划。研究计划将围绕以下四个中心主题展开：(1)新古典撕裂模式(NTM)稳定，(2)电流和动力学轮廓控制，(3)阻壁模式(RWM)控制，(4)等离子体流控制。拟议研究的结果将对使核聚变成为一种可行的能源所需的技术进步产生重大影响。此外，以应用为导向的理论研究活动将通过解决新的和具有挑战性的控制问题来显著影响控制，例如：(1)抛物型偏微分方程组的粘度控制，(2)分布参数系统的可实现的闭环最优控制，(3)具有结构不确定性的系统的鲁棒和自适应控制。拟议的研究计划侧重于对美国三个最重要的聚变设施的控制解决方案进行实验验证：DIII-D(通用原子公司)，NSTX(普林斯顿等离子体物理实验室)，阿尔卡托C-MOD(麻省理工学院)。广泛的影响：建议包括(1)教育学生在等离子体/聚变物理，计算技术，以及理论和应用控制的边界；通过在美国最重要的聚变设施进行的实验工作而得到加强(2)--课程开发(非线性分析和控制、分布参数系统控制、核能)和跨学科自动控制实验室(IACL)的升级。(3)外展：将通过以下方式实现外展：G6-12级教师、利哈伊谷独立学院协会(LVAIC)的非博士授牌学院成员和当地企业利用IACL进行远程访问；以及通过利哈伊大学已有的外展计划，为任职人数不足和经济上处于不利地位的K-12学生开展融合和控制方面的激动人心的活动。

ECCS-0645086E. Schuster, Lehigh UniversityAbstractIntellectual Merit: The objective of the proposal is to develop an integrated research and education program in feedback control of fusion plasmas. The research plan will evolve around the following four central topics: (1) Neoclassical Tearing Mode (NTM) Stabilization, (2) Current and Kinetic Profile Control, (3) Resistive Wall Mode (RWM) Control, (4) Control of Plasma Flows. The outcomes of the proposed research will have a strong impact on the technological advancements that are needed to make nuclear fusion a viable source of energy. In addition, the application-motivated theoretical research activity proposed will significantly impact controls by addressing novel and challenging control problems such as (1) viscosity control of parabolic partial differential equations, (2) implementable closed-loop optimal control of distributed parameter systems, (3) robust and adaptive control of systems with structured uncertainties. The proposed research plan makes emphasis on experimental validation of the control solutions at the three most important fusion facilities in the U.S.: DIII-D (General Atomics), NSTX (Princeton Plasma Physics Laboratory), Alcator C-MOD (MIT).Broader Impact: The proposal includes (1) education of students at the boundary of plasma/fusion physics, computational techniques, and theoretical and applied controls; enhanced by experimental work at the most important fusion facilities in the U.S. (2)-An Curriculum development (courses on Nonlinear Analysis and Control, Control of Distributed Parameter Systems, Nuclear Energy) and upgrade of the Interdisciplinary Automatic Controls Laboratory (IACL). (3) Outreach, which will be achieved by the use of the IACL, through remote access, by G6-12 teachers, non-PhD granting colleges members of the Lehigh Valley Association of Independent Colleges (LVAIC), and local industries; and by exciting activities in fusion and controls for underrepresented and economically disadvantaged K-12 students through already established outreach programs at Lehigh University.
