CAREER: Control of Processes Actuated with Mobile Radiant Sources

这个教师早期职业发展（career）奖的目标是利用移动辐射致动器对分布参数过程的估计和控制进行研究。该项目针对大型生产线的节能辐射干燥和固化工艺。该方法是i)识别将过程分解为主要能量传输和状态演化阶段的简化模型，以寻找统一的分析框架；ii)寻求有效的状态估计方案，以克服与缺乏合适的关键过程状态非接触传感相关的挑战。iii)开发闭环控制策略，协调辐射执行器的通量水平和轨迹，同时在不牺牲产品质量的情况下优化能源使用和生产力，iv)使用原型辐射干燥/固化系统进行实验验证，并通过FTIR， AFM和其他断层扫描技术分析加工和在加工样品。这项研究可能会在减少生产线的总能源使用和二氧化碳排放方面发挥变革性作用。解决控制移动辐射源的基本问题也将影响其他过程（例如机器人焊接和喷雾成形）以及在减轻污染和医疗放射治疗中的应用。此外，尽管有许多应用，分布参数系统的控制在许多机构的控制教育课程中很少涉及。本计画将透过开设分布参数控制的新课程及互动实验示范，协助推进有关主题的教育。计划的教育和推广工作的主题？控制能源效率？包括：与本科生研究机会网站和克莱姆森？s创意探究项目，让本科生，包括少数民族和女性参与研究；举办及参与暑期科学教师工作坊及？成功营地吗?;传播研究成果。该项目还将利用现有的合作，将有希望的发现技术转移到汽车和航空航天工业。

The objective of this faculty early career development (CAREER) award is to conduct research on the estimation and control of distributed parameter processes employing mobile radiant actuators. The project targets energy-efficient radiative drying and curing processes for large scale manufacturing lines. The approach is to i) identify reduced models that resolve the processes into the main energy transmission and state evolution phases in search of a unified analytical framework, ii) seek effective state estimation schemes that overcome the challenges associated with the lack of suitable non-contact sensing for key process states, iii) develop closed-loop control strategies that coordinate the flux levels and the trajectory of the radiant actuators while optimizing energy use and productivity without sacrificing product quality, and, iv) conduct experimental verifications using a prototype radiative drying/curing system along with analysis of processed and in-process samples via FTIR, AFM and other tomography techniques.This research will potentially play a transformative role in reducing total energy use and CO2 emissions from manufacturing lines. Addressing the fundamental problem of controlling moving radiant sources will also impact other processes (e.g. robotic welding and spray forming) and applications in pollution mitigation and medical radiotherapy. Furthermore, despite the numerous applications, the control of distributed parameter systems is rarely covered in the controls education curriculum at many institutions. This project will help advance education in the topic through a new course on distributed parameter control and interactive laboratory demonstrations. Planned education and outreach efforts themed around ?control for energy efficiency? include: interfacing with undergraduate research opportunity sites and Clemson?s Creative Inquiry program to involve undergraduates, including minorities and women, in the research; holding and taking part in summer science teacher workshops and ?success camps?; and, disseminating research results. The project will also leverage existing collaborations for technology transfer of promising findings to the automotive and aerospace industries.
