This award introduces new theoretical and computational tools for the design of structured optimal controllers for large-scale systems. Standard optimal design methods result in controllers that demand communication among all subsystems. In very large systems, this is a costly scheme due to its extensive communication, computation, and hardware requirements. The PIs will utilize special structures inherent to certain distributed control problems, such as invariances and symmetries, to develop a framework for localized control which compares to that available for centralized design. This research will result in the design of controllers that posses pre-specified localization and communication architectures, and are optimal with respect to global cost functionals. The educational aspect is centered around the development of a new distributed systems curriculum. This will include new introductory courses that will familiarize undergraduate and master-level students with the tools for analysis and design of distributed systems. These courses will emphasize practical applications and physical interpretations.This award will lead to significant technological advances by enabling the optimal localized control for systems with large number of individual components. Particular attention will be paid to the design of optimal control strategies for large-scale vehicular formations. The PIs will train participating students in a unique interdisciplinary fashion; they will also jointly organize workshops aimed at bringing together a broad audience of students, researchers, and industry professionals. These workshops will enhance a cross-disciplinary character of the proposed work and facilitate transfer of knowledge between the control theory and engineering practice. The outreach component includes the PIs' engagement in public seminars discussing the importance control engineering in transforming the collective decision making strategies employed by natural fliers, runners, and swimmers to engineering applications.

该奖项为大型系统的结构化最优控制器的设计引入了新的理论和计算工具。标准优化设计方法导致控制器需要所有子系统之间的通信。在非常大的系统中，由于其广泛的通信、计算和硬件要求，这是一种成本高昂的方案。 PI 将利用某些分布式控制问题固有的特殊结构（例如不变性和对称性）来开发本地化控制框架，与集中式设计的框架进行比较。这项研究将导致控制器的设计具有预先指定的定位和通信架构，并且在全局成本函数方面是最佳的。教育方面以新的分布式系统课程的开发为中心。这将包括新的入门课程，使本科生和硕士生熟悉分布式系统的分析和设计工具。这些课程将强调实际应用和物理解释。该奖项将通过为具有大量单独组件的系统实现最佳本地化控制来带来重大的技术进步。将特别关注大规模车辆编队的最优控制策略的设计。 PI 将以独特的跨学科方式培训参与的学生；他们还将联合举办研讨会，旨在将广大学生、研究人员和行业专业人士聚集在一起。这些研讨会将增强拟议工作的跨学科特征，并促进控制理论和工程实践之间的知识转移。外展部分包括 PI 参与公共研讨会，讨论控制工程在将自然飞行员、跑步者和游泳者采用的集体决策策略转变为工程应用方面的重要性。
