CPS: Small: Design of Networked Control Systems for Chemical ProcessesThis award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).The objective of the proposed research program is to develop, for the first time, the theory and methods needed for the design of networked control systems for chemical processes and demonstrate their application and effectiveness in the context of process systems of industrial importance.The proposed approach to achieving this objective involves the development of a novel mathematical framework based on nonlinear asynchronous systems to model the sensor and actuator network behavior accounting explicitly for the effect of asynchronous and delayed measurements, network communication and actuation. Within the proposed asynchronous systems framework, novel control methods will be developed for the design of nonlinear networked control systems that improve closed-loop stability, performance and robustness. The controller design methods will be based on nonlinear and predictive control theory and will have provable closed-loop properties.The development and implementation of networked control methods which take advantage of sensor and actuator networks is expected to significantly improve the operation and performance of chemical processes, increase process safety and reliability, and minimize the negative economic impact of process failures, thereby impacting directly the US economy. The integration of the research results into advanced-level classes in process control and the writing of a new book on ``Networked Process Control'' will benefit students and researchers in the field. The development of software, short courses and workshops and the on-going interaction of the PIs with an industrial consortium will be the means for transferring the results of this research into the industrial sector. Furthermore, the involvement of a diverse group of undergraduate and graduate students in the research will be pursued.

CPS：小：化工过程网络控制系统设计该奖项由2009年美国复苏和再投资法案资助（公法111-5）。拟议研究方案的目标是首次开发，介绍了化工过程网络控制系统设计所需的理论和方法，并在工业过程系统中展示了其应用和有效性。所提出的实现该目标的方法涉及基于非线性异步系统的新颖数学框架的开发，以明确考虑异步和延迟测量、网络通信和致动的影响来对传感器和致动器网络行为进行建模。在所提出的异步系统框架内，将开发新的控制方法，用于设计非线性网络控制系统，提高闭环稳定性，性能和鲁棒性。控制器设计方法将基于非线性和预测控制理论，并将具有可证明的闭环特性。利用传感器和执行器网络的网络控制方法的开发和实施有望显着改善化工过程的操作和性能，提高过程安全性和可靠性，并将过程故障的负面经济影响降至最低，从而直接影响美国经济。将研究成果纳入过程控制高级课程和撰写一本关于"网络化过程控制“的新书将使该领域的学生和研究人员受益。软件的开发、短期课程和讲习班以及PI与工业联合体的持续互动将是将这项研究成果转移到工业部门的手段。此外，还将争取不同群体的本科生和研究生参与研究。
