eccs - 0645086 e吗。摘要智力优势：该提案的目标是在聚变等离子体的反馈控制方面发展一个综合的研究和教育计划。研究计划将围绕以下四个中心主题：(1)新古典撕裂模式（NTM）稳定，(2)电流和动力学剖面控制，(3)电阻壁模式（RWM）控制，(4)等离子体流动控制。拟议研究的结果将对使核聚变成为可行能源所需的技术进步产生重大影响。此外，提出的应用驱动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，如：(1)抛物型偏微分方程的粘度控制，(2)分布参数系统的可实现闭环最优控制，(3)具有结构不确定性系统的鲁棒和自适应控制，对控制产生重大影响。提出的研究计划强调在美国三个最重要的聚变设施：DIII-D（通用原子公司），NSTX（普林斯顿等离子体物理实验室），Alcator C-MOD（麻省理工学院）对控制解决方案进行实验验证。更广泛的影响：该提案包括(1)教育学生在等离子体/聚变物理，计算技术，理论和应用控制的边界；(2)课程发展（非线性分析与控制、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，这将通过IACL的使用，通过远程访问，由G6-12教师，利哈伊谷独立学院协会（LVAIC）的非博士学位授予学院成员和当地行业实现；通过利哈伊大学已经建立的外展项目，为代表性不足和经济状况不佳的K-12学生提供融合和控制方面的精彩活动。

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.
