Proposal Number: 0638816PI: BarmishIntellectual MeritThe major objective of the proposed multi-disciplinary exploratory research is to develop system models and the associated nonlinear feedback control theory which is specific to new classes of Multi-Functional Materials. Such materials are typically anisotropic composites having microstructure of nano or micro inclusions optimized to perform multiple tasks. In this regard, the primary motivation for the proposed exploratory research is derived from the following fact: In addition to their traditional load-carrying function, they also exhibit electro-active or magneto-active behavior; e.g., their mechanical properties can be controlled via application of an electric or magnetic field. This leads to new classes of control and optimization problems. The intellectual merit of this work will be to introduce some new paradigm problems into the systems and control community. Our efforts will concentrate on the formulation and solution of fundamental problems which can be used as a takeoff point for new lines of research.Broader ImpactWith regard to broad and long term impact of the proposed work, we envision several new mainstream research directions supporting our main objectives. The first activity includes new control algorithms capable achieve desirable results with lesser actuation requirements. Should this exploratory research be successful, we envision a continuation of this work which focuses on design and optimization of materials composition and structure. This direction would be complimentary to ongoing research in carbon nano-tube based composites. To address the major objectives in material-oriented control, the expertise of the principal investigators is drawn from two distinct areas. Professor Barmish has made significant contributions to the robust control area and Professor Shkel has made significant contributions in multi-functional smart materials. The proposed research has both theoretical and experimental components. To this end, there will be constant interaction between the investigators involving modelling, testing of new control algorithms and iterative material design using equipment which is already available. Education-wise, this project suggests unique opportunities to introduce graduate students to a number of new inter-disciplinary ideas spanning electrical and mechanical engineering and material science. The plan is for Professor Barmish to introduce a number of new material science concepts into control courses and for Professor Shkel to introduce a number of new control concepts into material science courses.

提议的多学科探索性研究的主要目标是开发系统模型和相关的非线性反馈控制理论，这是特定于新型多功能材料的。这类材料是典型的各向异性复合材料，具有纳米或微夹杂物的微结构，可优化执行多种任务。在这方面，提出探索性研究的主要动机源于以下事实：除了传统的承载功能外，它们还表现出电活性或磁活性行为；例如，它们的机械性能可以通过施加电场或磁场来控制。这就产生了新的控制和优化问题。这项工作的智力价值将是为系统和控制社区引入一些新的范式问题。我们的努力将集中在制定和解决基本问题上，这些问题可以作为新的研究方向的起点。更广泛的影响关于拟议工作的广泛和长期影响，我们设想了几个新的主流研究方向来支持我们的主要目标。第一项活动包括能够以较少的驱动要求获得理想结果的新控制算法。如果这项探索性研究取得成功，我们设想继续这项工作，重点是材料组成和结构的设计和优化。这个方向将与正在进行的碳纳米管基复合材料的研究相辅相成。为了解决材料导向控制的主要目标，主要研究人员的专业知识来自两个不同的领域。Barmish教授在鲁棒控制领域做出了重要贡献，Shkel教授在多功能智能材料领域做出了重要贡献。本研究有理论和实验两部分。为此目的，研究人员之间将不断进行互动，涉及建模、测试新的控制算法和使用现有设备进行迭代材料设计。在教育方面，该项目提供了独特的机会，可以向研究生介绍电气、机械工程和材料科学等跨学科的新思想。Barmish教授计划在控制课程中引入一些新的材料科学概念，Shkel教授计划在材料科学课程中引入一些新的控制概念。
