The research objective of this project is to develop novel regulation methods for linear compartmental networked systems, which can directly and jointly address the physical and communication constraints typically imposed on these systems. Compartmental systems can be thought of as a collection of interconnected reservoirs exchanging flows of some material according to global conservation laws.Because this material represents a physical quantity such as a number of vehicles or a mass of fluid these regulation methods must be able to generate the desired closed-loop behavior without producing commands requiring these variables to become negative. In addition, communication between various reservoirs is often limited, and the commands must thus be computed based on local measurements only. The proposed approach builds on tools from the theory of robust and nonlinear control, and exploits the particular structure of compartmental systems to make design problems tractable for large problems, while incorporating time-varying parameter variations, random perturbations, and uncertainties. Particular effort and attention will be focused on the application of these methods to set-point regulation, output tracking, and disturbance rejection in compartmental models recently proposed for air traffic flow in the National Airspace System and large-scale, gravity driven, irrigation networks. Due to the wide range of processes that can be modeled as compartmental systems, we expect the tools resulting from the proposed research to benefit many important technical and societal applications in addition to irrigation networks and air traffic flow control. Examples include chemical production processes and some distributed computing scenarios. The technical results will be disseminated within the air traffic control community through close collaboration with the NASA Ames research center. Undergraduatestudents will be actively involved in the construction of an Irrigation Board testbed for irrigation simulation and its validation. This testbed will also be used as a teaching device, as part of a course for local high school students on the challenges of waterconservation and its possible engineering solutions.

该项目的研究目标是为线性隔室网络系统开发新的调节方法，该方法可以直接和共同解决通常施加在这些系统上的物理和通信约束。可以将隔室系统视为根据全球保护定律交换某些材料的相互联系的储层集合。因为该材料代表了诸如许多车辆或大量液体等物理数量，这些调节方法必须能够产生所需的封闭行为，而无需产生这些变量的命令才能产生这些变量。此外，各种储层之间的通信通常受到限制，因此必须仅根据本地测量来计算命令。所提出的方法是建立在健壮和非线性控制理论的工具上，并利用隔室系统的特定结构使设计问题可用于大型问题，同时结合了随时间变化的参数变化，随机扰动和不确定性。特别的努力和注意力将集中在这些方法在最近在国家空域系统和大规模，重力驱动的灌溉网络的空中交通流中的隔离模型中应用这些方法的应用。由于可以将其建模为隔室系统的各种过程，我们期望拟议的研究产生的工具使许多重要的技术和社会应用受益于灌溉网络和空中交通流量。示例包括化学生产过程和一些分布式计算方案。技术结果将通过与NASA AMES研究中心密切合作在空中交通管制社区中传播。本科生将积极参与灌溉委员会的灌溉模拟测试及其验证。该测试平台还将用作教学设备，作为当地高中生水库及其可能的工程解决方案挑战的课程的一部分。
