Project SummaryObjectiveThe objective of this program is to investigate and quantify the fundamental constraints, limitations, and tradeoffs in the design of networked control systems. We focus on the essential characteristics of communication channels (capacity constraint, quantization effect, data rate limit, etc) and at-tempt to develop intrinsic system measures, fundamental performance limits, and inherent design limitations for multivariable, multi-channel systems. In particular, we attempt to develop analytical expressions and bounds for the optimal tracking and regulation performance, with respect toprevalent channel models employed in the communications and control research. We also attempt to develop multivariable Bode and Poisson integral relations in the networked control setting.Intellectual MeritsNetworked control presents several fundamental differences and challenges unlike those found in conventional control. These differences need to be addressed, and should be exploited to advantage in the design of networked control systems. This program seeks to address key challenges and has its goal in quantifying the fundamental performance limitations and design tradeoffs in networked control. The program brings together experts in communications and control, and seeks to fuse ideas and advances in these fields. The proposed work, which is believed to be theoretically significant and practically feasible, has the potential to lead to the discovery of fundamental constraints and limits in networked control design, and to improved design methods and techniques.Broader ImpactsThe successful execution of this project will benefit researchers and practicing engineers in the broad areas of communications and control. The program also seeks to integrate a strong educational component in a concerted, systematic way. The synergistic activities include the offerings of Freshmen Discovery Seminars, development of instructional controls lab, projects for senior design courses, and direct participation of graduate and undergraduate students in the project. Outreach activities seek to provide local K-12 students' and teachers' research exposure by hosting visits to the PI's lab andactive participation in open house activities such as Engineering Day, and to provide high school students research experience by engaging the students in summer internships and special engineering programs. Our educational initiatives encourage especially participation from underrepresented students.

该计划的目标是调查和量化的基本约束，限制和权衡网络控制系统的设计。我们专注于通信信道的基本特性（容量约束，量化效应，数据速率限制等），并尝试开发多变量，多信道系统的内在系统措施，基本性能限制和固有的设计限制。特别是，我们试图开发的最佳跟踪和监管性能的解析表达式和边界，相对于通信和控制研究中采用的toprevalent信道模型。我们还试图开发多变量的波德和泊松积分关系在网络控制setting.Intellectual MeritsNetworked控制提出了几个根本的区别和挑战，不同于传统的控制。这些差异需要加以解决，并应利用网络控制系统的设计中的优势。该计划旨在解决关键挑战，并在量化网络控制的基本性能限制和设计权衡的目标。该计划汇集了通信和控制方面的专家，并寻求融合这些领域的想法和进步。建议的工作，这被认为是理论上的重要性和实际可行的，有可能导致发现的基本约束和限制在网络控制设计，并改进设计方法和techniques.Broader ImpactsThe成功执行这个项目将有利于研究人员和实践工程师在通信和控制的广泛领域。该方案还寻求以协调一致、系统的方式整合强有力的教育组成部分。协同活动包括提供新生发现研讨会，教学控制实验室的发展，高级设计课程的项目，以及研究生和本科生直接参与该项目。外展活动旨在通过举办PI实验室参观活动和积极参与开放日活动（如工程日），为当地K-12学生和教师提供研究体验，并通过让学生参与暑期实习和特殊工程项目，为高中生提供研究经验。我们的教育举措特别鼓励代表性不足的学生参与。
