Title:DDDAS/SEP: Optimal interlaced distributed control and distributed measurement with networked mobile actuators and sensorsAbstract:This one-year exploratory project focuses on applying the dynamic data driven applications system (DDDAS) approach to achieve optimal interlaced distributed control and distributed measurement with networked mobile actuators and sensors. The application system is on chemical fog concentration reduction or elimination. A group of moving sensors make distributed measurements of the diffusion process to characterize the diffusion process (sniffing), meanwhile, the dynamic data sensed is fed to a group of mobile robots equipped with neutralizer dispensers (spraying) to contain the chemical fog. Fundamental research issues include sensing policy, actuation policy, formation regulation and tracking, and optimal path planning. In this one-year exploratory DDDAS project, the PI specifically attacks the optimal interlaced distributed control and distributed measurement with networked mobile actuators and sensors, which will lay a foundation for characterizing and neutralizing multiple, possibly evolving, chemical sources, on and underground, by a team of ground mobile robots equipped with networked sensors (detectors) and actuators (neutralizers). The proposed research and educational efforts will have a significant impact on the development of mobile actuator and sensor networks for national security interests, water resources, precision agriculture, ecological and environmental monitoring; the creation of interdisciplinary research and environment; recruiting and retaining engineering students. As a motivating example, imagine that a hostile toxic diffusion source is being released and diffusing with no color and no smell. It is very desirable to send a team of mobile robots to sniff around and, meanwhile, dispatch another team of mobile robots to spray/neutralize the diffusion process. Since these robots are networked via wireless links, thus the name "mobile actuator and sensor networks." It is a hard problem to decide where to sniff and where to spray for each individual mobility node when various constraints exist such as limited battery life and obstacles. This project focuses on optimal interlaced distributed control and distributed measurement with networked mobile actuators and sensors. That is, move sensors for better measurements and in turn, move actuators for better control and neutralization. This project provides a new, unique exciting challenge to push the boundary of emerging distributed control system theories with a clear dynamic data driven flavor.

标题：DDDAS/SEP：最佳交错分布式控制和分布式测量与网络移动的执行器和传感器摘要：这个为期一年的探索性项目的重点是应用动态数据驱动的应用系统（DDDAS）的方法来实现最佳交错分布式控制和分布式测量与网络移动的执行器和传感器。应用系统用于降低或消除化学雾浓度。 一组移动传感器对扩散过程进行分布式测量以表征扩散过程（嗅探），同时，感测到的动态数据被馈送到一组配备有中和剂分配器（喷雾）的移动的机器人以包含化学雾。基础研究问题包括传感策略、驱动策略、编队调整和跟踪以及最优路径规划。在这个为期一年的探索性DDDAS项目中，PI专门利用联网的移动的致动器和传感器攻击最佳交错分布式控制和分布式测量，这将为通过配备联网传感器（检测器）和致动器（中和器）的地面移动的机器人团队表征和中和多个可能不断演变的化学源奠定基础。拟议的研究和教育工作将对移动的致动器和传感器网络的发展产生重大影响，用于国家安全利益，水资源，精准农业，生态和环境监测;创建跨学科研究和环境;招募和留住工程专业学生。作为一个激励性的例子，想象一个敌对的有毒扩散源正在释放和扩散，没有颜色和气味。非常希望派遣一组移动的机器人四处嗅闻，同时派遣另一组移动的机器人来喷洒/中和扩散过程。由于这些机器人是通过无线链路联网的，因此得名“移动的执行器和传感器网络”。“当存在各种限制（如有限的电池寿命和障碍物）时，决定在哪里嗅探和在哪里喷洒每个移动节点是一个很难的问题。本计画主要研究网路化移动的致动器与感测器之最佳交错式分散控制与分散量测。也就是说，移动传感器以实现更好的测量，进而移动执行器以实现更好的控制和中和。该项目提供了一个新的，独特的令人兴奋的挑战，推动新兴的分布式控制系统理论的边界，具有清晰的动态数据驱动的味道。
