CAREER: Control of Processes Actuated with Mobile Radiant Sources

这一教师早期职业发展奖的目标是研究使用移动辐射致动器的分布参数过程的估计和控制。该项目的目标是为大型生产线提供节能的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变阶段的简化模型，以寻找统一的分析框架；ii)寻求有效的状态估计方案，以克服与缺少对关键过程状态的适当非接触传感相关的挑战；iii)开发闭环系统控制策略，在不牺牲产品质量的情况下优化能量使用和生产率；以及iv)使用原型辐射干燥/固化系统以及通过FTIR对处理和过程中的样品进行分析来进行实验验证，AFM和其他断层扫描技术。这项研究将在减少生产线的总能源消耗和二氧化碳排放方面发挥潜在的变革性作用。解决控制移动辐射源的根本问题也将影响其他工艺(例如机器人焊接和喷射成形)以及在减轻污染和医疗放射治疗方面的应用。此外，尽管有许多应用，但在许多机构的控制教育课程中，很少涉及分布参数系统的控制。该项目将通过一门关于分布式参数控制的新课程和交互式实验室演示，帮助推进这一主题的教育。以能源效率控制为主题的有计划的教育和外展工作？包括：与本科生研究机会网站和克莱姆森？S创造性探究计划对接，让包括少数民族和女性在内的本科生参与研究；举办和参加夏季科学教师研讨会和成功夏令营；以及传播研究成果。该项目还将利用现有的合作，将有希望的发现技术转让给汽车和航空航天行业。

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.
